So this probably isn't the greatest piece of advice but it really helps me. The idea being , I am my thoughts. So if I entertain drinking, well guess what? I'm going to think about drinking.
When I say to myself "I will not drink, no matter what. I won't change my mind" every single time I even think about booze, it starts to become my reality. When I say stuff like, I will not drink 'today' my crazy brain says, maybe tomorrow. Resulting in the same white knuckle feeling of drinking still being some kind of option.
Take it off the table. Say NO. That is a complete sentence.
