Smoke weed... Works for everything else...
Buy sugar free lollipops.
get some sugarless gum
sunflower seeds area good distraction too. My man smokes, but when he coaches he can't so he'll eat sunflower seeds to keep his hands and mouth busy. Good luck...quitting will be the best thing you ever do for yourself. I HATE that my man smokes, but the more I ask him to quit the more stressed he gets and the more he smokes. LOL.
