I have smoked for 30 years. A pack and half a day. I started vaping in August 2013. I cut back to 3 or 4 cigarettes a day within 3 weeks. I completely stopped smoking on Feb 2 2014. I Vape 18 mg of nicotine in my E-Juice and I use the machinical mods and the rebuildable atomizers. Several different types of tanks and brands. I have been on Chantix and the patches in the past and nothing ever help me stop like the electronic cigarettes and or vaping. I didn’t last more than a week on the chantix or the patch. I can already tell a difference in the way breathe, smell, taste, and feel. Its so much cheaper vaping and I don’t stink anymore from the nasty cigarette smell. Vaping has been the best thing to come into my life and my families. We are 100% smoke free home in my home and my mothers home. The only negative thing I can say is that I didn’t find out about vaping until last year.
