There is a serious misconception that AA has a concept that it is the only way to get and stay sober.
There is nowhere in AA approved literature that I know of( and I've read a lot of AA literature) that states AA is the only way. There are actually a few different places AA says it isn't the only way.
And most in fellowship are very glad people get and stay sober other ways.
But maybe I missed something in AA literature you could point out for me?
