If you quit?
Yes! I tried ecigs back around 2006. With the short battery life and cost at the time, I wasn't impressed. I decided to give it another go this past November (spent the next weeks cig budget on a 510 kit), received it on my birthday (20th) got over the 'mental block' of it by December 2nd and I have only, out of curiosity, had 1 since.
How long you've been analog free?
I count December 2nd as the date of my liberation.
How long you smoked prior?
I smoked 2 packs a week at age 9 and was at 1 1/2 to 2 packs per day at age 43. There were times I had 'stopped', sometimes for as long as 6 months, but I would always start again.
Would you go back to analog if ecig hardware or software became unavailable?
Yes, absolutely. I hate to say it, but due to health reasons, in which I believe nicotine to possibly be beneficial, I don't ever see myself giving up nicotine. I wasn't looking to quit nicotine when I began this endeavor, I was seeking a better quality of health and life.
