Well I quit drinking again. I was up to almost a liter a vodka a day. This time I went to the doctor and got some medication to help with the withdrawl, which made it a hell of alot easier. I am going to AA meetings which sucks, but what sucks even more is I can't drink any more.
It worked really well for my exgirlfriend, but she tended to drink to oblivion when she was manic rather than as a daily thing, so I don't know if it'd work for you.
Good luck with your quiting. All the best.
