I got sober through a medication called Antabuse. It makes your body unable to breakdown the alcohol properly, and the result is an incredibly unpleasant reaction. Heart palpitations, extreme nausea/vomiting, massive headache, hot flushes, convulsions. Interestingly, during the clinical trials for this medicine, it became clear that a common response to combing alcohol and Antabuse was an impending sense of doom, and a belief one might die.
Needless to say, you simply cannot drink while on this medicine. Granted, you have to be compliant with taking the Antabuse, which can be tough sometimes. I found the best way for me was to take it daily for the first few weeks/months. Then, I would take it whenever I got a strong craving to drink. That would eliminate any chance of drinking for the next 3 days, and during those 3 days, I would find myself grateful I made the right choice, and I would pop another Antabuse.
This medication really, truly saved me from the bottle. I can't recommend it highly enough.
