Hi Gary,
Hope this day finds you well. There are lots of philosophies on addiction out there. If you are serious about quitting, AA is one option, but you may want to check out: SMART Recovery; Secular Organization for Sobriety; or Rational Recovery as well.
It's up to you to decide what will probably work best for you.
In a nutshell, AA takes the approach that drinking is a disease, and the cure is to seek support from others with drinking problems and connect with a Higher Power.
CBT, or cognitive behavioral methods take the approach that drinking is a behavior, and the solution is to quit on your own using behavior modification therapy/tools.
Now that you know you have to quit...it's only a matter of time until you actually do it, and start living the life you were meant to be living!
Warmly,
Blaze
