smoking cessation
"I took Chantix for 5 weeks about a year ago. I loved it at first; it helped so much with the cravings. I had to stop taking it due to the debilitating headaches it caused. The real problem is the headaches didn't stop when I stopped the Chantix. I'm still seeing a neurologist for daily headaches that present with both migraine and tension symptoms. I'm sure I'm in the minority, but it was most definitely not worth it."
