Hi santideva
there's no one way to do this - you'll find many success stories using many methods.
The first step tho is stopping drinking. If you're worried about withdrawal, get yourself checked out by a Dr, get the green light to quit, and then go for it.
AA's a good thing to try simply because it's everywhere and chances are you're never that far from a meeting, but there are other meeting based methods too.
