"Champix is beyond impressive!  I was advised to become aware of those "triggers" that drove me to reach for that cigarette in the first place before starting Champix. Stress is notorious for that, as well as that after meal cigarette. I came  up with many different positive ways to get around those triggers by switching them up. By day 3 in my 2nd week of taking Champix, I could only smoke half of a cigarette because it tasted and smelled that bad! One smoke that day is all I had. Side effects of nausea don't last for long for me. MAYBE up to a 1/2 hour at most, but not a craving for nicotine since I started my 2nd week. This is what impresses me the most! I'm starting week 3 tomorrow, and becoming smoke free with incredible ease."
