How does The Nul Medication Programme work?
Nul Medication Programme is based on targeted pharmacological extinction, following the principles of The Sinclair Method (TSM). By taking an opioid antagonist (such as Naltrexone or Nalmefene) before drinking, the endorphin reward from alcohol is blocked, leading to a gradual reduction in cravings and drinking over time.What is the Sinclair Method?
The Sinclair Method (TSM) is a medically supported treatment for alcohol reduction that uses medication to change how your brain responds to alcohol. Developed by Dr. John Sinclair, the method is based on the principle of pharmacological extinction – the idea that, by consistently blocking the endorphin-driven rewards of drinking, the brain gradually loses interest in alcohol.
This approach allows you to continue drinking while the medication works to reduce cravings over time. Unlike abstinence-based models, TSM supports gradual behavioural change without requiring you to stop drinking immediately.
The method has been validated in over 90 peer-reviewed clinical trials, with success rates as high as 78% in reducing alcohol use long-term (Sinclair, 2001).Is Nul’s Medication Programme scientifically proven?
Yes! The Nul Programme is based on The Sinclair Method, which is backed by over 90 clinical trials and has a 78% success rate (1) in reducing alcohol use. It has been studied for decades and is recognised as an evidence-based approach to alcohol reduction.
(1) Sinclair, John – clinical studies, 2001Does Nul follow an abstinence-based approach?

No! Unlike traditional abstinence-based programs, The Nul Programme allows you to continue drinking while gradually reducing your alcohol consumption. Over time, your brain reconfigures its reward pathways, making alcohol less compelling.
How does the medication work?

The medication prescribed is either Naltrexone or Nalmefene. They are both opioid antagonists that block the endorphin response alcohol typically produces in the brain. This reduces the rewarding effects of drinking, helping you break free from habitual patterns over time. As the brain stops associating alcohol with pleasure or relief, the urge to drink weakens. This is the foundation of the Sinclair Method®, which underpins Nul’s treatment programmes.
Sinclair,John - clinical studies, 2001What are opioid antagonists, and how do they help?

Opioid antagonists like naltrexone and nalmefene block the endorphin response that alcohol usually provides. This interrupts the reinforcement cycle and retrains your brain to lose interest in alcohol.
Is the medication new?

Naltrexone and nalmefene aren’t new – both have been licensed and in use for many years.
In the UK, Naltrexone was licensed in the 1980s for (1) relapse prevention in opioid-dependent individuals and (2) relapse prevention in formerly alcohol-dependent people. Whilst Nalmefene was licensed in 2013 for the reduction of alcohol consumption in adults, it is specifically licensed for those with alcohol dependence (who do not have physical withdrawal symptoms) and who also have a high-risk drinking level.
However, both medications have also been proven to be an effective way to reduce alcohol consumption in adults, including those who may not have "alcohol dependence" and a "high risk” drinking level, and they are commonly prescribed for this use.
When used as part of The Sinclair Method – where the medication is taken before drinking to reduce cravings over time – both drugs are prescribed “off-label.” This means they’re being used differently from their original licensed indications, but the approach is supported by clinical evidence and prescribed under medical supervision.Who should NOT take naltrexone or nalmefene?

People who:
-> Are pregnant, breastfeeding, or trying to become pregnant.
-> Are under 18 years of age.
-> Use opioid medications and/or substances and are unable or unwilling to stop.
-> Have pancreatic, liver or kidney problems
.-> Are allergic to the medications or their ingredients.
-> Are dependent on alcohol and experience physical withdrawal symptoms.
-> Require alcohol detoxification.
-> In addition to these, some groups, including those with significant mental health considerations, will be assessed on a case-by-case basis.Will alcohol feel different on this programme?

Many people report that alcohol feels less satisfying while on Naltrexone or Nalmefene. This is a sign that the extinction effect is working-the reward loop that was so entrenched in your neural pathways is slowly breaking down.
How long does it take to see results?

The effect on physical cravings is usually noticeable almost immediately after taking the medication, but the emotional and psychological shifts take longer. Some people begin noticing changes within weeks, while others may take several months. Like when trying to make any big life changes, consistency and patience are key.
Why isn’t this medication more widely used?

Most NHS services currently focus on abstinence-based treatment programmes, which is why GPs don’t usually suggest Naltrexone or Nalmefene for people who want to reduce rather than stop drinking. Private services like Nul offer evidence-based alternatives such as The Sinclair Method for those seeking a more flexible approach.
How do I know when The Nul Programme is working?

You may notice signs of extinction, such as:
✔ Drinking less frequently or consuming smaller amounts
✔ Forgetting to drink or leaving drinks unfinished
✔ Feeling indifferent toward alcoholWho provides the alcohol reduction service?

The clinicians managing your treatment are pharmacist independent prescribers with training in alcohol reduction
Do I need a prescription for Nalmefene or Naltrexone?
Yes, you need a prescription for Nalmefene and Naltrexone as they are prescription only medicines (POMs). This is so that a clinician can determine if it is likely to be safe and effective for you, oversee your treatment, and be there for you to reach out to between prescriptions.What is a liver function test (LFT) and why do I need to take one?
An LFT (also called a liver blood test) measures certain substances in your blood (such as proteins, liver enzymes, and bilirubin), which can indicate how well your liver is functioning, and whether there are any signs of liver damage, inflammation, or disease.
Taking an LFT allows the health of your liver to be assessed and ensures that you’re a suitable candidate for taking the medication. It also helps to establish a baseline to refer back to as you continue on your treatment journey, as in some instances you will need to take additional LFTs whilst on the service.
If you suspect or know that your liver is compromised, or you’ve previously had abnormal LFT results, tell the clinician about this during your live consultation. Do not complete the test before discussing it with the clinician.Do I need to see my GP before starting the programme?
Not necessarily. You'll complete an online assessment and meet with a registered clinician trained in alcohol reduction by our partners at Blueco Healthcare, who will review your medical history and liver function tests. The clinician will be able to review your medical record and contact your GP if they need more information.Does my GP need to know?

It’s important for every healthcare professional, including your GP, to have a complete understanding of any medications you are taking or have taken in the past.
With your consent, the clinician will write to your GP to inform them about the medication prescribed for you. This is so that they can update your primary health record, which is relied upon by many healthcare professionals, including emergency healthcare professionals.
If you don’t want your GP to be contacted, the clinician will discuss this with you to understand your reasoning. They’ll then use this rationale to determine whether or not it is safe to prescribe you the medication without letting your GP know. This decision is solely at their discretion and they may determine that they cannot prescribe to you in this instance.
How do I take my medication?
Take your medication 1–2 hours before drinking (as directed by your clinician).
If you are not drinking that day, do not take the medication.
What happens if I’m drinking over an extended period?If you’re drinking at an all-day event (like a wedding or holiday), a second dose may be needed 4–8 hours after the first. Always consult your clinician about second dosing.What are the common side effects of Naltrexone and Nalmefene?

Before drinking? Take it as soon as you remember and wait at least 1-2 hours as directed before drinking.
After drinking has started? Take it as soon as possible, but note that the extinction effect may be weaker. Try to never skip your dose entirely.Can I take my medication with food?

Yes! Many people find that taking your medication with food helps minimize nausea.
Is this programme suitable if I’m still drinking?

Yes. Not everyone wants to quit entirely, and abstinence is not a requirement for participation in the programme. You’ll take your medication 1–2 hours as directed before drinking, which, over time, helps reduce cravings and the compulsion to drink.

✔ Timeline-Based: Check in with yourself every 30 days.How do I track my progress?

Keeping a drink log or journal is one of the most effective ways to monitor your progress. Note the following after each drinking session:
- Number of drinks consumed
- Timing and setting
- Mood, cravings, and any side effects
- Small wins (e.g., choosing a non-alcoholic drink, feeling less urge to drink)What should I do when I experience a craving?

- Pause and assess: Ask yourself why you want a drink.
- Use the HALT method: Are you Hungry, Angry, Lonely, or Tired? Address these needs first.
- Delay the decision: If you still want to drink, set a timer for 15–30 minutes before deciding.
- Engage in an alternative activity: Try exercise, journaling, or connecting with a friend.What if I don’t feel immediate changes?

The Nul Programme is a gradual process. Some people notice changes within weeks, while others take several months to see significant reductions in cravings. Patience and consistency are key!
What are the Weekly Support sessions for Medication Programme?

Every week, we gather to create a safe space where you can simply listen, ask questions if you wish, and feel supported on your journey.
Our weekly sessions aren’t about putting you on the spot — they’re about giving you a supportive space to:
✅ Ask questions about your journey
✅ Learn from others’ questions and challenges
✅ Hear practical tips, real-life examples & coaching insights
✅ Strengthen your practice with TSM protocols
Whether you’ve only just started your journey or you’ve been with us for a while, these sessions are here to give you a dedicated learning space each week.
You don’t have to share anything unless you want to. Many people simply join to listen, reflect, and take away tools that help them stay consistent.
And if it feels more comfortable, you’re welcome to join anonymously, without showing your camera, or even without using your real name. This is your space to learn at your own pace.
Each week is shaped by your needs — sometimes we focus on specific examples, other times it’s an open Q&A.
What is IFS and how does it help reduce alcohol consumption?
Internal Family Systems (IFS) is a powerful therapeutic model that views the mind as made up of “parts” – each with its own perspective, emotions, and needs. Rather than fighting, shaming or suppressing the part that drinks, IFS helps you understand and heal it with compassion. This approach addresses the underlying emotional pain, trauma, or unmet needs that drive addictive behaviour. As you build connection with your Self – the calm, compassionate core of who you are – the need for alcohol naturally lessens.How do the therapy sessions work?
Sessions are conducted remotely with your dedicated therapist as well as part of a group. You’ll also have access to self-guided therapeutic content and tools between sessions to reinforce the ground you cover in your sessions.Can I have therapy sessions face to face?
No, all of our sessions are currently online. We have consistently found that this works just as well as in person sessions.What happens in individual therapy?

In 1:1 sessions, you’ll work closely with your therapist using Internal Family Systems (IFS) and somatic awareness to explore the parts of you that use alcohol and beyond this how you feel in your own skin in different aspects of your life. Together, you’ll learn to meet those parts with curiosity and compassion, uncover the unmet needs beneath the behaviour, and reconnect with your inner Self – the calm, confident and grounded presence at the core of your being. Individual therapy allows for tailored support that complements the group work.
What happens in group therapy?

Group sessions offer a powerful space for shared healing, reflection, and community. You’ll participate in guided IFS-based processes, body awareness practices, and group discussions that help you explore your relationship with yourself and with alcohol in a supportive, non-judgmental environment. Listening to others’ experiences can illuminate your own inner world and help dissolve shame. Each group is facilitated by experienced therapists who ensure emotional safety, confidentiality, and compassionate witnessing for all members.
Is this therapy like AA or rehab?

Not at all. There’s no 12-step structure, no labels, and no forced abstinence. Our therapy is trauma-informed, non-judgemental, and tailored to your unique relationship with alcohol and emotional history.
