smoking cessation
"Although I had some really crazy side effects, I highly recommend Chantix to those who are serious about wanting to quit.  I have taken Chantix for 3 weeks and am smoke free. I took before and quit but I took myself off and started back up once I was around smokers.  Now I will definitely take it for 3 months.  The side effects were the worst part. I had the very vivid dreams.  Some good but most of them were very very strange. Other side effects I had were nausea but that is only when I am around smoke right now.  And the last side effect I have is depression.  I notice that due to the other side effects I seem to be having more depression which I need to seriously take into consideration as to why and not really worry about it."
