Take the best tasting juice you have and buy a higher mg in the flavor. When you get the craving for a cig, vape the higher stuff for a bit. Ask yourself "why do I want that stinking thing when I can get my nic by vaping?" If you can't answer why, go do something you enjoy, taking your PV with you. You will be surprised that just getting your mind off of it and a little more nic in your system will stop you from reaching "FOR IT". Give yourself some time to get past that craving.
A month after I started I had a terrible day at work. Everything went wrong. I wanted a cig so bad I could taste it...literally. When I got home, I got my heavy hitter bottle of juice out, loaded a carto with shakey hands, and went for a long walk and thought about it. The walk and the higher mg helped me tremendously. Once home, no craving and I went back to my regular mg. All was good.
