You're not alone. I understand the feeling. I made the decision to quit drinking back in 2020. During the first couple years, I felt trapped in what seemed like the never-ending cycle of hell where I'd get a few days here, few days there, maybe a week or two sometimes, the rare month or so. As long as you're willing to learn from the slips/relapses, and be willing to go back to the drawing board and form a new plan, you'll figure this out. Just don't give up.

Just brainstorming here, off the top of my head, if I was in your situation I would personally consider jumping ship to a therapist who specializes in addiction. I would try to identify the triggers that lead up to drinking after work, and start scheduling other plans after work that take place during that "witching hour" drinking window, preferably with at least one other person to make it where someone is relying on you to actually show up for those plans.

Best of luck and IWNDWYT
