Unfortunately in my experience I chose to try drinking ONE more time (more than once) and feel the results before I really accepted that I can't drink again, ever, unless I want to live those consequences. Like when someone rubs a dog's face in it's own mess to teach it not to crap on the rug..that was what I had to do to myself.
eventually, reminding myself of the reality of what will happen if I drink again, renews my acceptance. A list, photo, etc of the reality of our drunk days can serve as that reminder if we need a concrete one.
Instead of torturing myself with the "I cannot drink again EVER" (beats breast and heaps ashes on head) I use the blander "I'm a nondrinker"...that's pretty easy to swallow. There are many non drinkers, it's really not that dramatic or extreme...it really helps me when I cut the drama out. I was all kinds of addicted to drama.
