smoking cessation
"I took Champix after 9 months of trying to break my 40-a-day, 22 year addiction with nicotine.  I started taking it on Christmas Day 2015 and had my last cigarette on Jan 6th (day 12 of the course).  I had to stop taking champix on day 16 because the depression and constant crying was driving me almost to the point of smoking....  Have been left with will power alone, and annoyingly have no reference now as to time for cravings to disappear etc as I'm not sure what the effect of champix is in that respect.
However if I have to start again with this quit attempt, I would love to try Champix again."
