Chantix
"I gave this drug rating of 5 because I have seen it do well for many people. However, I went CRAZY after starting this medicine. I watched 4 people take this medicine and do very well and quit smoking. If it was not for a friend that I had not spoke to in weeks calling me I would have done even worse. When she contacted me I explained my symptoms of fatigue, depression, and even crazier things. She then told me the exact same thing happened to her on Chantix. I have quit smoking before. My advice: Try this medication but HAVE SOMEONE WATCH YOU FOR SIDE-EFFECTS."
