I'm in a similar situation mate. Been trying to knock it on the head for years now with very limited success. 3 day binge stopped yesterday morning. Just got to keep trying as I know my race is run in regards to drinking.
Haven't been to AA for years, horses for courses. AA is the wrong course for this horse! I might go back to SMART if I can face telling people I've been drinking like a fish again. Maybe I should listen to Jack Trimpey from Rational Recovery, make a big plan NEVER to drink again and actually stick to it. This addiction malarkey can get demoralizing and knackering!
Best of luck to you and hang in there. We can do this!!!
