I finally had to stop Chantix after the second week because of the nausea also. I could concentrate at my job it was so bad. It made me want to hurl just thinking about taking two a day after what the single doses were doing to me. I read in the earlier post that she was taking them only at night. I wonder what the outcome was for her? Was it more bearable? I still have almost a whole box. I also heard something about a person breaking the pills in half and the nausea wasn't as bad. The sickness I felt could only be compared to pregnancy..'nough said. I'm not giving up on trying to quit, just looking for another route. Any ideas on these options?
