Ive been on and off them for a long time. Always only 1 or the other. I learned that eventually that going back to analogs (did that several times) I missed the e-cigarettes cleanness and taste, and my health went back in the dumps every time I went back to analogs from the 1st screwup every time. I barely missed analogs after awhile, now im addicted to e-cigs instead and dont really mind that fact at all
. Stick with it, its very much a life changer, go into it with a positive state of mind as opposed to an experimental state of mind. Best of luck
