Sounds like you really suffered a lot that summer, Fire Fairy. Sorry to hear that. I agree with Steph - be very careful with CC so you don't get inadvertently glutened. Your safety is at stake as Steph's friend's experience demonstrates.
If you haven't had one since going gluten free, I would say that there is a chance of a link between the two.
Nikki, you just gotta love dogs. They give so much back to humans.
