I once wrote a song for my wife called "You are so pulchritudinous"..... j/k
Well for me as an atheist, skeptic, and sober person I think I figured out early on that it makes no difference what you believe, when it comes to being successfully sober your chances are going to be just as good as anyone else's as long as you truly commit yourself to lifelong sobriety.
I think the first step is all that matters, recognizing alcoholism is your problem and realizing that the only solution is to never drink again. From there you just figure out a way to do it, consult whatever resources are available to you, be they groups or books or whatever, and develop an approach that fits your own convictions.
It doesn't have to have an acronym, it doesn't have to have a name unless you want it to. It doesn't have to be scientific if you don't need it to be. As long you are truly committed to sobriety, you'll be alright.
