I’ve been a 1+ pack a day smoker for over 15 years. I’ve tried everything to quit, patches, gum, prescriptions, cold turkey but none were effective. I started vaping in Dec 2014 and haven’t smoked since! I’ve also managed to reduce my nicotine level from the 18mg I started at to only 6mg and plan to have it reduced to 0mg and quit by the end of this year! I’ve had no ill side effects from vaping. I no longer wake up every morning barely able to breathe coughing up nastiness like I did when I smoked. My clothes don’t stink anymore. My teeth have whitened dramatically. I’m not exposing my family to 2nd hand smoke. I honestly feel healthier. The following might not sound like a big deal to most, but it is to me. It has left me deeply concerned about how Chantix has knowing and unknowingly effected me for the long term! 5yrs ago I tried Chantix and within weeks experienced horrible side effects! Depression, nightmares, migraines. Since taking it I’m also no longer able to drink Mello Yello or similarly flavored beverages despite them having once been my favorite (3-4 cans/day). I almost instantly get nauseous now and experience headaches after drinking even a small amount.
