Ok, few pretty typical things:
First, you actually have to want to quit. Gotta get past the 'magic wand' thing. Vaping isn't a magic wand - if you aren't really committed to quitting it won't happen.
Don't make the butts easy. They don't go on the desk, on the night stand, next to your easy chair etc. They go on the top shelf of an inconvenient place. Make yourself get up and go get one every time you really want it. If you have your gear at hand, but have to get up to get that cigarette... you might be amazed how lazy we all can be.
Are you vaping enough? It's a beginner mistake to try and vape the same way you smoked, with long lapses between vaping sessions. A lot of noobies have to work up to vaping enough, and vaping on a consistent basis throughout the day. Vaping isn't smoking: You don't get a fast buzz out of it they same way you get instantaneous gratification from a cigarette.
If key times of day produce craving fits consider having a second tank with the next higher nicotine level for those phases. For me that was first thing in the morning when I had bad craving fits, and the last couple hours of the day before bed. I had to use two different nic levels for my first four months to deal with cravings.
For a few people they just can't get past cigarette withdrawal without something beyond a plain nicotine liquid. If you think this is the case you want to look into NET - Naturally Extracted Tobacco - liquids.
HTH
on what may be going on.
