I started Chantix to help me quit smoking yesterday. My quit date is 5/1/14, and I'm excited, but I'm also REALLY nervous. Last time I tried to quit (cold turkey), I was an emotional wreck my about 26 hours in. Couldn't stop crying, it was a disaster. According to my doctor, that's what the Chantix is supposed to help with, but I'm still pretty nervous. I'm not even sure the medicine will work, and I'm afraid it's just going to give me mental problems (black box warnings)...but I'm trying really hard not to psych myself out. It feels good just to get that out.
