Have you done all the steps, in order like they are writen on the first 164 pages of the big book?
The reason I ask is this: rarely have we seen a person fail who has thoroughly followed our path. (the path is the 12 steps of AA)
If you go to meetings, share, get a sponsor, read the book you've done some good things. But you haven't actually DONE AA.
AA IS the steps.
When you relapse what step are you on?
Because there is probably someone that can help with that.
