I haven't been diagnosed as having a gluten allergy, but I gave it up just the same to see if it helped (since so many CD peeps seem to have success with it). After 30 days of no gluten, I noticed a considerable difference for the better with D and cramping. To test, I tried a little bit of gluten in a dinner roll and was fine. The next weekend I had gluten all day long (again, to test) and noticed a change for the worse. I read that even when you don't have an allergy to gluten, you can still have an intolerance that irritates the lining of your intestines. I figured the safer the better! And knowing that gluten may have been causing my pain made it a lot easier to give up. Outside of holiday parties and special events, I don't really miss it. There's so much to eat that's gluten free.
Do your best, then to hell with it.
