My father drank a lot. He quit after he left the army. I think he drank to suppress nightmares and he was able to quit -- without any kind of program, like AA -- once there was no threat of returning to a war zone.

I also have known people who were apparently drinking to treat some undiagnosed medical condition and drank less or quit drinking after the condition was properly treated.

I think it would help to assume you have some reason for drinking so much. Now you need to figure out why that is and try to solve the underlying problem.

I like the book "The truth about addiction and recovery" as a resource.

Best.
