has anybody had a flare up after quitting smoking? I noticed that by ibs is a LOT more active in the absence of nicotine. I asked my gi, and he said that there are studies that indicate that nicotine quells flare ups and that a significant number ibs-prone people who quit smoking have flare ups. he said he would never recommend smoking to his patients, but sometimes he is tempted to do so. anybody had this experience?
