I can't tell you the number of times I said "no more" and drank the next day, week. I couldn't control my drinking no matter what I tried, and I tried everything.
The simple truth staring me in the face was ... I cannot drink at all. Accepting that truth was life-changing.
Have a good talk with yourself, make a plan and stick to it.. no matter what. You can do this, you don't have to live this way.
