I don't know if you quit or not, but maybe you should speak to your doctor and maybe he can prescribe something to help you relax.
I quit with Chantix
, 1 year, 2 weeks and 2 days ago. I had very few side effects
and after 38 years of smoking, I am grateful that I was able to quit.
I would recommend that you have a talk with your physician about what is going on. Because Chantix is fairly new, it is important that they document all of the possible side effects.
