A couple thoughts from my own struggle:
-If you have a few cigarettes, don't tell yourself that you are "smoking again." Tell your self that you only had a few cigarettes.
-Get some nicotine lozenges. I can get them with 4 mg nicotine. If I get the urge for a smoke, I make myself take one of them and chew it up. The rush of nicotine cancels the urge to smoke and then before that goes away, pick up your vaper and get going.
