"I can't believe it. I have been smoking for 12 years, anywhere from 1 - 1 & 1/2 packs a day. I took my first dose of Chantix on Saturday 3/7/09. My quit date was 3/4/09. On day 3 of taking the pill, I only smoked 5 cigarettes that day. Not really because I didn't want to, but because I didn't have the urge for it. I smoked my last cigarette at 10:15pm on Saturday 3/14/09. I feel wonderful. I can deal with the side effects, minor as they are. I began having wild dreams the 2nd day on the pill. I got sick in my stomach just once, but that's because I took it before breakfast. I have come to realize that taking it about 10 minutes after I eat is best for me. I didn't take any pills today and I feel great. I'm so grateful for this medicine."
