Chantix side effects?!

Chantix side effects?

I am on my 4th day of not smoking- My second week of Chantix starts tommorrow. I am thinking about giving it up because I am so sick to my stomach, headache, trouble sleeping and dreaming? Any advise?

I took Chantix for about 3 months. The stomach ache will calm down after a few days. Your body just needs to adjust to the increased dose. I also found the trouble sleeping to decrease after about week 2 and actually turned into a really good deep sleep that I miss! The weird dreams continued up until I stopped taking it.

Good luck with quitting! I haven't smoked since October.
