As I read up on vapeing before I jumped in a short time ago, I would have pegged myself at a high nic level based on my analog use. I am on the higher side, but not extreme as it turns out. I use 24mg, and sometimes 18mg, but I find that it works. I go through about 2 1/2 mls a day of juice a day and some of that is the need to replace the hand to mouth part of our former habit... If you feel good, get the nic you need to satisfy you, and can stay off analogs.... Trust in yourself! Good luck and enjoy vapeing.
