There's also rational recovery. I have the book that lays that one out but haven't gotten into reading it yet.

My main issue with AS, NA, and 12 step in general, is the insistence of a higher power. While the program says it can be anything you choose, finding a sponsor that understands atheist/agnostic beliefs and will work with that is another story.

I have had several sponsors that I have told I don't believe in the traditional concept of God and prayer, yet they still insist of praying together and anytime I would call with cravings, their first question would always be "have you prayed?"

That is part of the reason I don't have a sponsor currently, but the other part is the mental illness. It's is equally difficult to find a sponsor with even a basic knowledge of how mental illness and addiction compound each other.
