How long does the Sinclair Method take to work?

Patients almost always want to know how quickly they'll feel a difference. The honest answer is gradual — the method is biological extinction, not pharmacological cure, so the timeline is set by how often you drink and how reliably you take the tablet.

Week 0-2: titration

We start at a quarter tablet for 5-7 days, then half, three-quarters, and full. This minimises side effects (mild nausea is the most common) and lets your body adjust. You will not feel a dramatic change in your drinking yet. The medication is just at the right dose; the extinction work hasn't really started yet.

Week 2-4: the start of unlearning

Once you're on the full dose and taking it reliably one hour before each drinking occasion, the extinction process begins. You may notice that drinks feel slightly less satisfying, or that you don't reach for a second drink as automatically as before. This is subtle. Most patients can't quite put their finger on it. They just notice they drank a bit less than they expected to.

Week 4-6: noticeable change

By the end of the first month, most patients describe a clearer reduction. The number of drinks per session is often the first thing to fall — you drink three glasses of wine instead of five, or you stop after two pints when you would have gone for four. The frequency of drinking occasions tends to drop a bit later.

This is also where the dip happens. Some patients hit week 3-6 and feel discouraged because the reduction isn't more dramatic. This is normal. Compliance through this period is the strongest predictor of programme success.

Week 6-12: meaningful reduction

By the end of the second and third months, most patients see substantial reduction. Many find their drinking has roughly halved. Some are down to a glass or two on weekends only. A minority discover they no longer want to drink at all. The pattern varies.

Month 3-4: extinction

This is the point where the brain's learned reward association has faded substantially. Cravings are quiet. Drinking, when it happens, feels much less like the loaded ritual it used to be. Patients often describe this as 'taking back control' — drinking is something you choose to do, not something that pulls at you.

Most patients stay on naltrexone past this point, either at the same dose (to maintain the extinction) or tapering. Our Ongoing subscription provides continued support and repeat prescriptions for patients who want long-term maintenance.

If your timeline is faster or slower

Some patients see faster change — drinking halved by week 4. Others take six months to see substantial reduction. About one in five don't respond meaningfully and need a different approach. Compliance, drinking pattern, genetics, and underlying mental health all influence the timeline. We'll talk about your trajectory at each follow-up.
