Well, I gave up cigarettes by going to a hypnotist, but it might not work with alcohol. As a consultant, our firm was preparing a bid to provide comprehensive alcohol rehabilitation services for the City of New Orleans. I had an opportunity to work with the staff of Hazelden rehab in Minneapolis, the mother church of rehabilitation. The most significant fact I learned was that detox, or becoming alcohol free is not the key step in rehabilitation.
The thing that makes alcohol rehab work is disassociation from the group of friends the addict has, and the formation of new friendships and confidants. That is one of the key points of Alcoholics Anonymous that provides a sponsor/confidant and a new set of friends to support the recently sober. Bottom line, no matter what you use to quit, you're going to need supportive friends to stay off the sauce.
