Being new to the vaping world I have found this also. I think it's because you can vape so many places you can't smoke, it's almost like beating the system. Then I think we fall into the flavors we vape are so much more enjoyable than the analog cigs we were smoking. I am now 2 months into the process and am finally slowing down (on most days). Thought I needed more nic and went up to 24mg which is really too high for me. Went back to my 18mg with an occasional 24 and am doing much better. I think it's just part of the territory - it's a new experience that will mellow out on it's own.
