I, too, am allergic to
wheat, it is very common as bsml said, so is whey
. Sometimes, they are not allergies
, but "sensitivities" however, both can make you feel crummy.
As I stated earlier, I have allergies, quite a few, but, I am used to them, and I try not to eat those that I know are the most offending very sparingly, usually, that helps to keep things at bay.
