Not quite an intolerance?

[cairech]

I am gluten intolerant with a number of typical symptoms like gas, anxiety, joint pain, et cetera.  However, when I eat dairy I notice I get fatigued and a little fuzzy-headed.  My boyfriend has this same reaction to gluten!  So we're having a similar reaction caused by different foods.

Do you have a similar problem?  Any idea what reaction this is?  It's not an allergy or an intolerance, but it's something related to eating particular foods.

thanks!
