I could image becoming sober without the AA program even though it is proven to be a very powerful in its ability to help addicts of alcoholism. Except, I for one would believe in my strength to do whatever it takes to become sober. However this does not mean that I believe that A.A. is an ineffective program by any means.
Staying sober in Alcoholics Anonymous or A.A. is challenging to think of at first as it is a huge commitment for someone. So why not just focus on achieving your goal of living freely without the dependence of alcohol first? I mean AA is anonymous so there are no records kept, but I believe it is safe to say that AA has helped millions of people.
