I switched to e-cigs full time last May after being a PAD Marlboro smoker for nearly 30 years.
I got my first PV on a Thursday, a homemade box mod that a co-worker had built for me, and started experimenting with it that weekend.
Then, during week one of the switch, I substituted the e-cig for all my smoking except for 4 cigarettes a day: morning, lunch, afternoon commute, and before bed. I stuck with that routine for a week.
For weeks 2 and 3, I cut back to only 2 analogs a day: morning and before bed.
By week 4, I cut out analogs completely.
Since the full time switch, I've revisited analogs 4 or 5 times, (the last one being in early January). I've yet to smoke a whole one, though, because they taste ABSOLUTELY HORRIBLE!! Honestly, I can't help but think that if cigarettes tasted THIS bad when I first began smoking, I never would have started. Then I realize that they probably tasted just as bad back then, and I can't imagine why the hell I ever continued to smoke them.
