AprilMay,
While I was posting on another thread a moment I ago, I remembered you had this thread going. There used to be "aversion therapy" methods a few years ago, and maybe they still exist. The concept is to add a bad sensation to the drinking or smoking experience, to create a negative association. Like an electric shock. Or something. It would be interesting to find out if they still do that kind of stuff.
(For those who want to throw "Antabuse" out there -- yes, similar idea, but I mean stuff like electric shock therapy. Having said that, AprilMay, there IS antabuse type therapy out there, but it is not usually used exclusively I don't think. I don't think it works very well, and it can be dangerous.
