I went to AA last year, then didn't start going again until fairly recently. I went back to meetings because I relapsed and my whole attitude is that if something wasn't working, then something needs to change and for me that was going to meetings.
If you want to give it a go, try a couple of different ones and see what you think!
Otherwise there's often now some kind of community support. I go to a drug and alcohol addiction centre run by the area I live in and that's nothing to do with AA.
