I will try eliminating dairy. It will be hard though because she really does love her wake-up milk. Worth a try. So far, so good tonight. She didn't have any dairy since around 1pm which is a change for her.
As for your gluten sensitivity, did you do a blood test and did your doctor recommend going to a specialist to rule out Celiac? Mine did, but I am too much of a wimp for an endoscope since the end result would be eliminating gluten anyway. It would be nice to know for sure though. At least my constant headaches are gone.
