"I started taking Chantix some time after Christmas. I didn&#039;t want to quit, I was one of those smokers who enjoyed it. I&#039;ve been a smoker for 19 years. After about 2 weeks I cut back to about 7 a day, but on January 26 I quit. I was doing really well and then I got this horrible cold and relapsed. I&#039;m still taking Chantix but I wasn&#039;t taking it as prescribed. I plan to now take it 2 times a day instead of once. I&#039;ll keep taking it only because I&#039;m scared I&#039;ll go back to smoking. I&#039;ve read all of these horrible side effects and got scared so stopped taking them and then the urge to smoke came back. I&#039;ve had mild side effects like upset stomach, vivid dreams. I&#039;m determined to be a non-SMOKER."
