I have a friend with this and am wondering if I have it as well. I'll be sending this link to him as I'm always looking for info for him on IBS . My version (if this is what I have) is very mild compared to his,but it's changed gradually over time since I got a really ugly case of food poisoning around 10 years ago and over the last year has changed yet again. Gastro has me on prescription probiotics,which,much to my amazement,actually work! I plan to have a nice chat with my gastroenterologist next month and will see if they will give me a label. Ok,so let me throw some juicy links at ya cause I love to throw links at folks.
