Chantix
"I'm on day 8 with Chantix.  Smoked a pack a day for 25 years.  I haven't really noticed a huge change yet.  No nausea, no crazy dreams, no mood changes.  Cigarettes are starting to taste a little funny, and sometimes I'll light up and not want to smoke the whole thing.  I guess I'm just waiting for the big bang!  We'll see, this is only the first day of my second week with the tiny blue pill.  I'm sort of jealous of the posts I'm reading from people who said they stopped smoking on the 3 and 5 day.  I'll give it some time.  Day 9 is tomorrow."
