I'm trialling a gluten-free diet to see if it helps with my thyroid, and am feeling much better since I started. I have been invited to a 40th afternoon tea party. I can take my own gluten-free stuff along, but was just wondering what could happen if I had a day off and treated myself to some sandwiches, scones and cakes? It's an hour and a half away on the train so I don't want to end up making myself ill!
