I smoked over a pack a day for 30 years. I purchased an e-cig kit and as of the first day of using it, I have not smoked a cigarette. The e-cig resolves my desire and need for cigarettes. The e-cig worked where the patch, chantix or the nicotine gum did not. The e-cig has helped tremendously and I feel much healthier and I do not feel like an outsider when around non smokers.
