A smoker for 40 years @ 40 a day, I was finding that I could not climb even small hills without pausing. After 3 months of vaping I could walk up the hill to my home without a pause. 18 months further on down the line I am capable of running up that same hill that used to give me problems.
I am a 59 year old hotelier in a town that is full of hills, and vaping has been a lifeline to me. I am now active in trying to help maintain the availability of personal vapourisers for every one who chooses to try them. I even keep a small stock of parts and liquids at my hotel for anyone who breaks theirs over a weekend or are otherwise unable to buy replacements.
My wife is delighted to tell me that I no longer stink of tobacco, and neither does our apartment.
It is just short of 2 years since I started vaping, and I am now feeling better than I have in fifteen years.
