Wow. I feel like crap!

Sorry, but I do. My wife and I are both trying to quit smoking, so the doctor put us on Chantix. We are in our first week so we are still allowed to smoke, but we are far enough along that when we do smoke we are nauseous. My wife has actually gotten sick a couple of times after a cigarette. I know it is for the best, and we'll be healthier once we kick the habit, but damn this sucks! Anybody else taken Chantix? What was your experience like?
