Okay, so on Monday Morning I took my first Chantix. It made me so ill, I can't even remember the last time I felt that horrible. Literally, about 40 minutes after taking the pill (and yes, I was smoking but You're Supposed To in the first week!) I started throwing up, which continued relentlessly for about 6 hours. Needless to say, I won't be taking Chantix anymore, which is quite dissappointing. I thought I had found something that would finally work for me. Has this happened to anyone else? I assume I am allergic, but maybe not?
