I had much the same experience when I first switched to vaping full time. The interesting thing to me is that I have been able to lower my nicotine level over the last almost three years without setting any goals. And my e-liquid consumption hasn't increased significantly.When I put the analog cigarettes down in favor of vaping, interestingly enough, I found I was addicted.
Addicted to a mysterious chemical in which I was always told was nicotine.
However I soon found out that considering I had nicotine going in to my body, through ecigarette liquid, yet still had a severe craving for that 'something'. That something is what at that time and continues to strike a bit of mental fear in me. What in the blazes was I putting in my body!?
After a short time, while continuing to use the ecigarette, maybe one month give or take a few extra weeks, I no longer had the drastic 'I must have a cigarette' feeling, yet this craving continued sporadically for many months. Until I completely forgot about it.
The question here, again, is what is being put into the 'tobacco' slurry, which is addicting enough to keep an analog cigarette user entranced. Find this chemical, and we find the real death dealer.
The handful of times that I tried to switch to "light" cigarettes, my cigarette consumption went up dramatically.
I know that's not scientific in any way, but to me, it says something about the difference between vaping and smoking.
