I've been using SMART for 3 months, and previously was in AA for 3 months too.
I have to at least credit AA for "breaking" me and getting me to be able to talk about my problem for the first time, it's also very immersive for newcomers, which may be helpful.
But after 3 months of being preached to, suspending my livelihood with 1-2 meetings daily, "faking it" as hard as I could, and being a little mind-twisted... I also decided I didn't want what they had.
I'm happy with SMART, the tools are useful, practical, you customize your own program, I think that might be a difficult thing to do for someone feeling completely hopeless (like I was). But now I'm sober, and *SANE*, I like that part.
