Well, Nancy, there's a subject line that I'm sure will get you lots of attention!! :-)

Have you been eating anything unusual or lots of something? For example, since it's harvest time of the year, I'm eating lots more tomatoes than I usually do and in another week or two I'll be eating tons more Asian pears than I usually do.

Are you eating more soy or casein than usual? Those two proteins are so similar to gluten that many people are sensitive to them, too, and this can sneak up on you when you don't expect it.

I'm sorry you're struggling with this. It's no fun.

Hope you get it figured out!

Rachel
