I've been vaping since March 2013. Only one analog in that time (when the car blew up on the interstate). I was paid-forward by a workmate and have been doing the same ever since. I don't actively preach the benefits, as some people have problems or get disheartened and go back, but I'm helpful and informative.
On a personal note my physician says my lung function has improved since quitting! And this from a 40 year cig smoker!
May you be similarly blessed with improving health.
