smoking cessation
"I felt like I lost 2 months of my life on Champix.  Was lucky to get four hours of sleep (after wacko dreams) a night; depressed, lethargic,  bloated, and constipation like you would not believe.  NOTHING WORKED - for two months I tried everything, even bio-prep (like you have before bowel surgery) or enemas.  I was walking around in an absolute fog.  But I have to say, Champix worked and I have tried everything over my 28 years smoking.  I stopped taking the tablets 3 or 4 weeks ago and am fine, no desire to have a cigarette at all.  Best of all it does kill the nicotine monster - I found I was starting to get addicted to the little lozenges (my Happy Pills) when I was on those.  Good luck if you are considering taking Champix."
