champix experience

When I first went to the doctor they gave me this prescription for champix. It took me 2 weeks of careful reaserch and consideration before I got the script made up and 1 more week after that as i was worried about the affect it could have on me. I told those closest to me I was taking it and to let me know of my moods and behavior. The only side effect I've had is the sleepless nights. I'm 13 days smoke free and coming to the end of week 4 of champix. I've been out once with friend who smoke 3 days ago and not once did i get the urge to smoke. Good luck to everyone trying to quit!
