My fiance & I both need to quit. I always have sinus headaches & he has a chronic cough. You would think that would be enough to discourage us from lighting up, wouldn't you? That's how addicting these nasty things are. I've decided I'll quit first & put up with his "DT's" later!! He's tried Chantix but I don't think he was ready to quit yet. I hope I'm as successful as you!!
