I'll tell myself:
No matter what happens, I'm not going to smoke
This is hard, but I'm determined
Smoking won't make this better -- it will make it worse
No smoking!
I really just used this one yesterday. My AS was missing again, and I got the craving for a cig. Then I asked myself if that would bring him back sober and clean. -- I could easily answer NO, so didn't have a puff.
Thanks for being here with so many helpful hints.
