My beast, hated when I told it that I'm quitting forever and no one or thing could stop me, especially not him. It's painful but liberating if you can really accept it as fact.
I think I'm lucky however, because everyone I know that has quit did it on their own. When I asked them what they did they just said, "quit". I thought it was stupid and kind of snide at first. Then I realized all you really have to do is never, no matter what, drink again.
