The Sinclair Method: Pharmacological Extinction of Alcohol Addiction
research · Volpicelli et al., 1992 (naltrexone for alcohol dependence); popularized by Katie Herzog's Drink Your Way Sober (2025) (1992)
Naltrexone, an opioid antagonist, can reduce alcohol cravings when taken before drinking. Unlike abstinence-based approaches, patients continue to drink while the drug blocks the rewarding effects of alcohol, leading to gradual extinction of the craving over time.
Core Concepts
The Problem
Alcohol addiction affects millions and standard treatments like AA have limited success; many patients relapse because they cannot tolerate abstinence.
The Claim
Targeted pharmacological extinction via naltrexone can enable moderate or reduced drinking without requiring abstinence from day one.
Key Evidence
- •Volpicelli et al. (1992) found naltrexone reduced relapse rates in alcohol-dependent patients.
- •Subsequent studies show reduced heavy drinking days and craving.
Practical Implication
Expanding treatment options beyond abstinence-only models could improve outcomes for a large population of alcoholics who don't respond to traditional approaches.
Nuance & Limits
The method faces cultural resistance from 12-step communities and requires patients to continue drinking initially, which can be psychologically difficult for loved ones.
