Yup I've done it. But without the help of patches or gum. I switched completely over to an electronic cigarette, it has a smart chip, battery, atomizer and nicotine cartridge, inhale too much and the smart chip cuts you off. It's a pretty neat system. And I only puff on it when I need a fix. I have noticed that my sense of smell has increased, food still tastes the same and I'm thirsty all the time. I crave sweets. I drank 3 glasses of chocolate milk for some reason last night just out of the blue. I'm sure I'm gonna get hell from some of the senior members for using the e-cig, but it's helping me, I don't want to smoke and the smell of smoke sorta makes me sick to my stomach. Anyway that's my update.
