I consider myself an atheist. I went to a single AA meeting and had a really hard time there. The one I went to had a LOT of god talk and a brief mention of the 'chapter to the agnostic' in the big book. I love my family very much and always have, but in spite of it I've been getting drunk for years. So, for me, the 'higher power' didn't work.
I didn't decide I wanted to quit until I decided that I wanted and needed to quit for me. I'm probably not explaining that fully and sounding selfish. Fact is, I have many reasons and things that have finally made me want to quit for good, not just one. I've kind of come to the opinion that are many reasons that all us want to quit, and the more reasons each of has the better. But, I know I would keep backsliding until I know in my heart that I am the cause of my problem (which I know) and that I am the solution.
