Ugh. So today is day 1 of no smoking; day 8 of Chantix. I hadn't felt like it was working until now but today it was much easier to not smoke. This evening, however, I felt so sick and actually vomited twice. So here is my question: have other people thrown up because of Chantix? My dr told me to expect nausea but i didnt think i would actually vomit. Or could it be not smoking? Also I took the pill on a pretty empty stomach (I left it at home and took it right when I got back). Is that the culprit? Any help would be so so so appreciated.
