While AA wasn't the best "full-time" solution for me in the long run, it certainly was instrumental in my early recovery. Like you, I started using AA in a mandatory setting as a resident in a recovery center. After I left, I found it very helpful to continue in the early goings of my new sober life. By attending AA on my own outside of the center, I felt that I was taking some personal responsibility for my recovery independently. That alone was a great step. You certainly have nothing to lose by giving this a shot outside of detox.
