Hi PPQ,
I think if you have taken the time to register here and post you are taking the next stage of your recovery. I never went into a detox program but it sounds messed up. I guess you would be feeling pretty raw now.
Keep sober. You may feel like crap but imagine how you will feel after another binge.
I can't add more than the others except that AA is not religion and you can be agnostic or an atheist and still apply the steps, you don't need to believe in a God, just in something greater than your own inflated ego. You have to be able to let go.
I'm not religious but I have accepted a spiritual solution to my problem because nothing else worked. I found that the power I need was always there inside me. I was trying to create happiness and peace from the outside in rather than from the inside out.
I would not confuse AA with organized religion. Its simply not that, if you cannot be convinced, try a secular path - there is a sub forum here where programs are discussed.
Good Luck
