Every route to changing your drinking in the UK, side by side: cutting down or stopping, rehab, the four medicines doctors use, The Sinclair Method, therapy and support groups, NHS or private.

The Sinclair Method (TSM) is gaining traction as a science-backed way to change our relationship with alcohol. But a common and completely valid question we get is: how long does it take for The Sinclair Method to work?

Founded by Matt Brindley and Bruce Rose, Rethink Drink champions an evidence-based, client-centred approach known as The Sinclair Method (TSM). They’re not just another recovery service—they’re redefining what it means to take back control.

In the United Kingdom, the Chief Medical Officers advise that to keep health risks from alcohol low, adults should drink no more than 14 units of alcohol per week. This guideline is the same for both men and women, and it is best to spread the intake across three or more days rather than consuming it all at once

The Sinclair Method is a treatment for Alcohol Use Disorder (AUD) that involves taking naltrexone before drinking, at a time set by a prescriber. Naltrexone blocks the endorphin reward from alcohol, and over time drinking tends to fall, a process known as pharmacological extinction.

Naltrexone is a prescription medication known for its ability to block the brain’s opioid receptors, which are responsible for the “reward” feeling associated with alcohol consumption
