I have had success in removing all grains from my diet, especially wheat. I am following the candida diet. It is hard in the beginning because you have die off reactions that are most likely causing your symptoms.
Have you tried going on to the Candida Forum ? If you do, click the link at the top of the page where it says Candida Homepage. It will take you to a lot of information I think will help. Plus suggestions for books to read. Here is the page link //www.curezone.org/dis/1.asp?C0=75
Also have you tried enemas or colon cleansing? I have been doing coffee enemas since I began the diet and they helped tremendously with die off reactions.
