Good for you Aleric
I found "playing the tape forward" to be huge during those times. Invisioning the complete disaster that the one drink would bring. Followed by a full blown relapse and months if not years of trying to get sober again. It just isnt worth it if you spend just a few moments looking into the future.
I know it sounds dismal but I could never have just one. I would spiral completely out of control.
Good for you for staying sober😀
