I smoked for 15 year. I tried quoting several times with various levels of success. I used zyban, gum, cold turkey, and chantix twice. None of these meathods ever got rid of the desire for a tobacco cigarette, only made the urge to light up more manageable, and I returned to regular smoking within six months. I bought Halo’s G6 electronic cigarette system in October of 2011. I used it exclusively for a week and was pleased. I was out with friends one evening and I decided to join then in a tobacco cigarette when they stepped out to smoke. I couldn’t finish the tobacco as it was making me ill. I smoked a tobacco cigarette three months later with the exact same result. It has been a year and a half since I have lit-up, unlike any other time that I quit, I no longer have any desire to smoke tobacco. I still use my electronic cigarette daily but I am lowering the nicotine levels, and do not use it nearly as often as when I began.
