hey, am no expert or anything but i am a smoker who is giving up using champix, it is normal when you are giving up for your lungs to be under pressure because your body is working overtime to clear your lungs of chemicals caused by nicotine, every 10 minutes your lungs are getting clearer (so i have read) and with you breathing in and out it is making it harder, so your chest seems tighter and you cant take a deep breath without feeling uncomfortable, this should clear up in time ( about a week) if you continue to not smoke. If it doesn't i would seek more medical advice hope i have helped you out Jenny

I have been cigarette free for 8 months after using Chantix. I have not breathed better in my life. You will get your air back and more. Just stick with it.

Have you by any chance gained weight due to quitting? If so, you may not be used to the weight gain. Just watch what you eat. and like others suggested, be patient, and don't pick it back up!

Best of Luck!

undrtktres, how's it going? still having those chest pains?

i rememember last time i quit, i had the same thing for a few months... it was like my lungs were "unglueing" themselves apart. lovely...



anyway, after that lovely story, i started smoking again... after going to a few smoke fillde clubs in eastern europe... so, i'm sick now with the flu and going thru day one of not smoking. my plan is to ride it out while i'm sick - i've foudn that it's much easier to get over the hump this way in the past. hope it works again
