I have been suffering with IBS for the past 10 years. It has reached a chronic state and nothing seems to help.I have been feeling terrible all day (nauseous, headache, fatigue, backache, etc). Obviously you have to put your best foot forward at work and disguising how you feel is very draining.I decided to search the internet and found this site. It is very comforting to know that there are other people out there with IBS. Most of the time when I've said that I suffer from IBS I've been treated like a hypochondriac.
