I would definitely say see your doctor or call him or her to make sure that you can take both. But be ready for a time of your life when you fall asleep. My dreams were so vivid and so disturbing that I would wake up in the middle of the night and not be able to fall back asleep. Also, Chantix has been linked to suicides, ideations of suicide, and diabetes as you probably already know. I would suggest that if you want pick up a book called The EasyWay to Stop Smoking by Allen Carr. I just picked it up today and cannot, I mean, cannot put it down. It shines a whole new light on quitting and staying smoke-free. Good luck!
