I had smoked since I was 14.. tried quitting cold turkey and with Chantix over the years. After losing my father to lung cancer last year and seeing several friends have success with vaping.. I decided to try it. I got a mod in January and have not had a cigarette since 3 days after I started vaping. I started at 18mg of nicotine and I’m now down to 3mg.. will soon be at 0. I can now breathe so much better.. my allergies have greatly improved.. I can exercise much easier. My sense of smell has come back and I just feel much healthier! 🙂
