"I thought that Chantix wasn't affecting me. I was on it for 2 weeks and experienced no side effects (even with taking the pill on an empty stomach and accidentally double-dosing). It didn't MAKE me want to quit or make cigarettes taste bad.

 

I decided to quit the day after Thanksgiving. To my surprise, I didn't have any of my usual withdrawal symptoms. Usually, I am like Mr. Hyde in my temperment. I thought of having a cigarette, but it was a 'thought' and not a craving. For me, Chantix didn't make me put down the cigarettes, BUT it did take away my withdrawal symptoms, leaving me only having to deal with the mental pangs of wanting one. I tried a cigarette 2 days after quitting and it tasted horrible. Not going back to smoking ever."
