Also known as the best-kept secret in the recovery industry, the Sinclair Method (TSM) is a treatment for Alcohol Use Disorder (AUD) that uses the medication naltrexone, taken one hour before drinking, to gradually reduce alcohol cravings.
This method has a 78% success rate, backed by dozens of clinical trials on both animals and humans.
It allows you to decide whether you want to continue drinking in moderation or quit entirely—at your own pace, without feelings of deprivation, but simply because you no longer feel the need to drink.
What Is the Role of Naltrexone in TSM?
The Reward System and Endorphins in Addiction
When we consume alcohol or other substances, a chemical "party" takes place in the brain. These substances trigger processes that alter how we feel, with alcohol specifically promoting the release of endorphins, which are responsible for feelings of pleasure and well-being.
To understand how alcohol creates dependence, it's essential to understand the brain's reward system and the role of endorphins in this process.
The Reward System: Your Brain’s Internal Teacher
The reward system is a powerful tool that evolution has given us to ensure survival. It helps teach us that certain behaviors—such as eating, exercising, engaging in sex, or giving and receiving affection—are important and should be repeated.
When we engage in these activities, the brain releases endorphins, creating a feeling of pleasure that motivates us to repeat those behaviors.
Over time, these behaviors form neural pathways in the brain. At first, developing a habit—like exercising regularly—can feel difficult, but as we repeat the action, these pathways become more defined and accessible.
How Alcohol Hijacks the Reward System
The problem with alcohol and other drugs is that they "hack" the brain’s reward system. The endorphin release triggered by alcohol is significantly stronger than that of natural activities like eating or exercising. As a result, the neural pathways associated with alcohol use become increasingly reinforced, encouraging repeated consumption.
For people who are genetically predisposed to alcoholism, this response to alcohol is even more intense. Their brains release an excessive amount of endorphins, creating a sensation of euphoria far beyond simple relaxation or social disinhibition. This strengthens the neural pathways associated with alcohol even further, turning what might have started as a choice into a nearly uncontrollable urge.
Additionally, prolonged alcohol use diminishes sensitivity to other sources of pleasure and impairs brain regions responsible for decision-making and self-control, making drinking a compulsive behavior.
How Naltrexone Works in the Sinclair Method
This is where naltrexone, the key component of the Sinclair Method, comes in.
This medication acts as a "blocker" in the brain’s reward system. When taken before drinking, it prevents alcohol-induced endorphins from binding to the brain’s receptors responsible for feelings of pleasure and euphoria.
Over time, this process weakens the neural pathways associated with drinking, turning the "highway" back into a simple dirt road. The brain gradually relearns its original response to alcohol, as it was before addiction developed, effectively breaking the compulsive link to drinking.
A Gradual, Science-Based Approach
What sets the Sinclair Method apart is that it uses this mechanism gradually and in a controlled manner. Instead of requiring immediate abstinence, TSM allows people to drink while taking naltrexone.
This approach progressively reduces cravings and the pleasure associated with alcohol. Over time, the desire to drink naturally fades, allowing individuals to choose moderation or abstinence without feeling deprived. The brain literally "unlearns" addiction, and cravings disappear.
At this stage, you get to decide whether you want to drink in moderation or stop completely—without hitting rock bottom, without rehab, and without suffering from withdrawal.
A Scientific and Effective Approach
Understanding how the reward system and endorphins play a role in addiction is crucial to seeing why the Sinclair Method works so well.
TSM doesn’t just treat alcohol dependence as a behavioral problem—it addresses it as a chemical and neurological issue that can be effectively treated with a science-based, compassionate approach.
Naltrexone is not a magic cure, but when used correctly, it is a powerful tool that can truly transform lives.
