I've been thinking about this a lot lately. I've relapsed many times over the years, my last one was about five years ago after 1 1/2 years AF.
I think my issue was that I didn't really want to stop drinking. I knew I should, I knew I was causing health issues that would get worse if I didn't, I knew I was spending too much money and wasting too much time on it, etc. But the root cause was ultimately I didn't truly want to give it up. I was doing what I thought I should do, not what I actually wanted to do. In psychology it's referred to as cognitive dissonance and it's
not good
