I quit alcohol without AA, I tried three sessions with them and sadly it did not work out for me. I used some simple self help methods which enabled me to discover the reasons why I drank and made dealing with the problem quite easy.
I'm an addictive person and was surprised that my methods worked, but here I am over 2 years later without a relapse and convinced that I will never drink again.
I believe that sharing your experiences on a forum like this is enough to help you to get over your addiction.
