After more than 20 years of smoking, I'm trying to quit. But instead of feeling good, I'm feeling sad, even depressed. What's going on?
Anyone who has quit smoking knows that there is a strong possibility they’ll gain weight. One of the really interesting things about the nicotine in cigarettes is that it works in two ways. When you take a long drag, it acts as a tranquilizer, but when you inhale in short puffs, it acts as a stimulant.
