IMHO, a good 12 step program is a wonderfull thing. I am a still recovering alcoholic, this Feb 22, I will have 5 years of sobriety. I was forced to get into the program of AA by the state in which I live. I was one sick, deranged puppy. I was very doubtfull that those 12 steps would be helpfull in any way. I could not have been more mistaken. The big blue book written by the founder of AA must have been divinely inspired, and has helped millions of people all over the world, recover from alcoholism and drug addiction.
Once science has found a way to effectively help those of us diagnosed with PTSD, I believe a good recovery/aftercare program could be designed around the principles of a 12 step program.
Just one man's opinion.
