I was a PAD smoker for 30 years. I have tried Chantix (twice; once for a month, second time for three months), nicotine gum, and hypnosis. I had tried BluCigs back in 2009, and used them for a month, but they were not very effective. My daughter referred me to some new devices that were on the market, with bigger batteries and better nicotine delivery systems. I did research on several devices, picked a name-brand USA made VV device and eJuice. I quit analogs the very next morning. That was Oct27, 2012. Over 9 months smoke-free! I have not had an analog cigarette since and have absolutely no urge to have another. I have weaned down from 24 mg to 12 mg. I function better with nicotine. I don’t drink coffee or alcohol; never have, never will. But I DO want my nicotine! And I DO want my vaping habit! I feel much better, my lungs feel clear, and I get fewer colds now. I can hike again without wheezing. BTW, my wife, a PAD and a half smoker of 35 years quit with me, and is enjoying her new vaping lifestyle also!
