I’m in hell. I’m on a quarter of the total amount of Chantix that will eventually be taken and I’m already miserable. My head is buzzing. Feels like I’ve smoked 10 Marlboro reds and I’ve only been on it for 2 day. I haven’t quit yet (I’m tapering cigarettes while higher doses of Chantrix every day. If I feel bad now with .5 a day, what happens when it’s 2 mg a day???
