It took years of trial and error, appointments, and research. The first thing you need to do is get a _diagnosis_, and I would go up to Mayo Clinic in Rochester if I were you. They are #1 in gastroenterology, which is a very complex subject. That's what I finally did after waiting 8-10 years and getting nowhere locally. Mayo diagnosed me with fructose malabsorption, so I finally had a handle on it and could have a chance figuring out what to eat and not eat. I quit eating all sugars and fruit to begin with, but it was challenging determining what vegetables I could eat because most of them have sugar. I had a lot of help from the medical librarian at the local university med. center who did research for me on lots of things. I did not find dietitians that helpful because fm is a new area for them as well and they thought it would be ok to eat some sugars and for me it was not. I cannot do low FODMAP for example. I've been to Mayo maybe 3 times totally regarding G.I. symptoms and have finally reached a point where things are basically under control and I am trying some new foods occasionally. Still have bouts of indigestion and "pay for" trying something new. Only introduce one new thing at a time so you can determine if it is ok. Good luck with this. My heart goes out to you.
