Good luck on the knee replacement. I’ll keep you in my prayers. And at least it’s only 3/day, huh? As an ex-smoker (a long time ago), that craving never fully goes away. But once you get down to 0/day, just link it in your mind with something really unpleasant and it’s easier. To this day, that first whiff I smell triggers a small craving, then within a second or two, it reminds me of something so unpleasant i don’t even want to mention it here. lol!
It does not help when my husband still smokes.
