smoking cessation
"Started age 18 Smoked 37 years Up to about 1 1/2+ packs a day when I first tried Chantix realized in the first week that it was probably going to work so I stopped it because I wasn't ready to quit smoking. When I was ready the second time I stopped at the end of the first week because I had no desire and it was pointless to try. That was January 2012 and I haven't thought or wanted a cigarette since. So Chantix did what it said it would and for me no bad or vivid dreams or anything  BUT (and I'm not alone ) that week is the same week I lost or severely altered my sense of smell which used to be better than average. Coincidence? It might be a synergistic reaction specific to some people. And I can't taste since January 2015, 3 years later."
