It's been a few since I've read the Big Book. So, I used the Big Book search engine. Not only could I not find "rock bottom", but I couldn't find where it mentions bottoms at all. And, while I do agree that medicine and science has greatly advanced over the years...a hole in the soul is still a hole in the soul.
AA® BIG BOOK® SEARCH ENGINE
If you find AA archaic and conflicting, you may want to check out other forms of recovery like SMART, AVRT, or CRAFT.
I was reading about AVRT the other night. They say the program is effortless. All an addict has to do is to make a Big Plan and say "I will never use again. And, I will never change my mind" and then they are completely recovered.
