AA doesn't work for everybody. I think one possible problem might have been that you viewed it as a "class" (like you were back in school, or something.) It's somehow more than that to me, though. It's hard to explain...

That aside, I know many folks don't like AA variety of reasons...which is OK. The important thing is quitting if you think you have a problem. AA has worked for me, even though there's a lot in the program I disagree with, or feel uncomfortable about.
