You also might be suffering from the night-time ritual thing. That was the weirdest part of quitting for me. It was that "one last cig before bed" that befuddled me.
Cigarettes have a very clear beginning and end point. When I was first vaping, I had trouble with it because I always had my pre-bed cig telling me when it was time to go to bed. With vaping, there is no end point. You have to put it down of your own free will. It makes it a lot harder to decide when to cut off, and you don't get that same feeling of "completion".
With the vape, there's no clear signal that it's over like with a cigarette. Perhaps, if you really want to take the plunge and get rid of it, you need to substitute a different bedtime ritual with a clear end point - a cup of Sleepytime Tea, or use that time to refill your carts fresh for the new day. Just pick an activity that has a clear end-point to substitute. It might take the edge off.
As long as you've been vaping, I think what your going through isn't nicotine craving, it's ritual craving. And there's no way to change that except to just... do it. Sure it'll feel weird for awhile, but you'll never get used to it if you don't jump in (or jump out, in this case). You need to embrace the new rhythm, and ignore the old. It gets easier very fast once you make the leap.
