You can quit without AA
I have to admit AA is one of the reasons I will be sober for 1 year and 6 months on the 10th of this month. I have a friend who hads been sober for 30 years and has never been to an AA meeting in his life. I know man who has been sober 10 years, never been to an AA meeting in his life. AA, no AA, the first thing you have to do is say no ever time you get the urge to drink.
