I have CFS and wonder if I have Celiac disease. Tests show neg but I don't eat enough bad foods before testing to cause a positive. My allergy tests are fine, both immediate and delayed. 25% off the time I eat bread or pasta, don't feel tired after. 75% of the time, I feel more tired 30-40 hours later and it lasts for several days. I never have diaharrea or the usual symptoms of celiacs. What do you think? You guys are so helpful, thanks!
