Smoked 13 years, averaged 15 cigarettes per day. About $120 per month. Began vaping on 25 March 2013: zero cigarettes since. Spent $400 so far (saved $80). Estimated future monthly cost: $30 per month. Started with an eGo-C. Used mostly that for the first three months, though I did try other equipment. Recently switched to a bottom-coil clearomizer. Started at 12mg/ml nicotine, and continue using that level to-date. I mix my own liquid from a 36mg/ml base and flavorings. Tried to quit six times, but never made two full days. Methods included willpower (four times), The Easy Way by Allen Carr (once), and the patch (once, used the entire box of patches in a spate of separate attempts, but never lasted more than a day). None of those methods provided a psychological break from the habit. They simply said, ignore the habit long enough for it to go away, and in that regard they were all based on willpower (Carr’s book attempts to undermine that notion, but by a strict definition it cannot be said to be different than willpower). Vaping provided the necessary psychological break: instead of doing that (smoking), do this (vape). I’ve regained my sense of smell/taste. Small reduction of congestion, but I never had much of a cough or sinus problems to begin with. No other notable changes (weight constant, et cetera).
