Welcome to SR! You have a good post....and will get a lot of different answers.
I think a lot of it is so individual. Personally, I have used only SR to get sober (9 months after drinking for 30 years). No AA, no sponser. I do have, however a very strong will. I've decided I'm going to be sober, therefore I am.
Certainly, though, social skills are where a lot of us fall. Myself included.
I'll peek back in on this thread....it's a good one. Not sure this forum gets looked into a lot, you may want it moved to the alcoholism forum, maybe?
