I go to AA. I spend as much time at SR as I can. I do not believe AA is the only way and if I thought SMART, out patient treatment, or anything thing that would keep me sober would be a lot better that the life I led before.
I am willing to try or willing to go to any length to feel the way I feel right now, forever.
I don't think you have to go to AA meetings but you must do everything you can to stay sober and grow as a sober human being.
Find what works for you and then even add on to that every time an new opportunity comes up.
