smoking cessation
"I used Chantix for about 2 weeks and the side effects were horrible; depression, insomnia, anxiety, etc. But it did get me to quit smoking. You could attribute those symptoms to quitting, since they are common symptoms of stopping smoking, but I will nip that argument in the bud. I was an emotional wreck, barely able to function at all. Cold turkey wouldn't be as intense as what I experienced on Chantix. I would recommend Chantix as a last resort for anyone wanting to quit smoking."
