I got glutened at Carrabbas off of their gluten free menu (I suspect the cook put the grill sauce on my chicken)and I threw up half way through my meal! Wierd thing is, I was known for NEVER throwing up in my gluten eating life so now that I am gluten free I throw up when I get glutened. I think your body just says, "WHOA! I thought we got rid of this crap...
