I smoked for over 27 years …the last 5 years I noticed decreased energy, coughing more and more and for longer periods, Lot of phlegm build up. Finally able to quit after failing many times over the past 20+ years I tried nicotine gum within 3 days I was smoking still tried it for 3 months before giving up,same with the patch. NRT was a joke did not help at all. With an ego twist and clearomizer I was able to quit in 3 days I’ve now been smoke free for 9 months with no side effects and no desire to pick up a cigarette again. energy has returned, food tastes better, coughing is lessening each week, phlegm is going away (albeit slowly). Absolutely feel healthier now that I have in the past 5 years! BECAUSE OF VAPING I CAN BREATH AGAIN!!!!!
