Have quit smoking for 4 weeks now with the help of Chantix (which I only took for 2 weeks on account of it making me feel crazy). Anyway, while I'm happy that I'm no longer smoking, I feel like crap. In addition to energy and sleep problems, I'm also feeling pretty depressed. Curious about other peoples' experiences with post cessation depression. What is "normal" if there is such a thing, and at what point should I be seeking help for this?View Thread
