smoking cessation
"Chantix was a quit smoking miracle drug.  However, I did go from six pack abs to a beer gut within two weeks.   It did help me quit smoking but it either decreased my metabolism so much that I gained weight, or it acted like a sugar pill to make me gain wait.  I started running (which I never did before) close to five miles a day. I had never run while I smoked. Yet, I gained the weight. I do agree with Chantix as it helped me quit smoking and feel better, but I did put on some pounds... I went from model to six pack within two weeks."
