Quit? If you mean switched completely - YES!
How long smoke free? Two years and two months, since Nov. 08 (but vaped off and on, without being smoke free, for eleven months before that).
How long you smoked prior? 44 years, close to 2 packs a day, with numerous quit attempts interspersed lasting from a few hours to a few years.
Would you go back to smoking if ecig hardware or software became unavailable? Another stockpiler here; plus I think I will always be able to find some sort of supplies from some corner of the world; if truly impossible, then unfortunately I might, as much as I hate the thought.
