Lets look at AA from a logical point of view. I personally know 50+ people with 10+ years of sobriety and I am sure my experience is no different than any other alcoholic who has been in AA for a while. It is obvious to me that they are doing something that works for them and they tell me, "It can work for me as well."
I have found it wise in my drinking and non-drinking life to listen to experts in their fields even when their advice did not seem to make sense. Although I fought it tooth an nail I did what they told me to do and son of a gun it worked.
Your best attempts got you to where you are so maybe it is time to try something new and listen to the people who seem to be successful in their battle not to drink. Try 90 meetings in 90 days and see if life gets better. I have never seen this offer fail.
I know for an absolute fact that you can do it with the help of others.
