A lot of it is state of mind, you really have to want this and commit to it. I treated vaping much in the same way I treated smoking triggers such as the first thing I grabbed in the morning, after I ate something, in the car, still went outside on work breaks... I just vaped instead of smoked and was able to quit day one after 30++ years of smoking. The tactile feeling of my personal vaporizer was a big help also, I started out on a cig-alike to keep that same cig feeling in my hand and vaped a menthol eliquid. To this day now 4 years later if I get a craving to smoke I break out the cig-alike and vape some menthol and it goes away.
