I quit taking Chantix about a week and a half ago. My cravings have not returned (thank goodness-- I've only been smoke free for a month)! But wow was I depressed for a good four days-- is this normal?? I read that Chantix gives you those side effects while on it (didn't happen to me) but why when you go off of it? All is fine now but it's a little scary... Anyone else have these issues?
