I'm an alcoholic, and I also used used to smoke, when drinking, so it was pretty much all the time.
Amazingly to some, I quit smoking while I was still drinking.
For a while I used "extra helpings" of booze to pass out more quickly so I didn't miss the smokes as much.
I guess I got past the physical addiction to the cigarettes, and was happy I could pass out earlier. Win/win situation, huh?
Maybe 3 times since I stopped drinking I picked up cigarettes again, only maybe 5 a day, but each time I stopped, it was incredibly hard.
I was so terrified by the time I got to the point when I quit alcohol, I would have done anything.
To take a drug to get you off booze? I just don't know. You'd still have the personality that went with the drinking, and you'd have no incentive or even understand why you'd need to change your ways.
AA's fine, it serves it purpose. Personally, after going there for a year, I used it as a place to pick up guys. Then married one of those AA "gurus" who like many, are a street angel but house devil.
I'd sit at a meeting with him, going on about the big book, people standing around afterward to shake his hand, then listen to him on the drive home talk about what stupid assholes they all were.
That's when I realized how much I had changed, but how much more I had to go......Divorced him, and lived happily ever after (with another sober alcoholic)
Moral of above? If I had just taken a drug to stop drinking, nothing else in my life would have changed.
I needed the jump start, but realized eventually how glorious life could be.
