Welcome to the team, Dawn. I have the same thyroid disease, and I have notice I'm much more stable off wheat especially, and gluten in general. I think one of the things which may help is that we just say no to so many things which would tempt us in the past.
Last weekend we went out to breakfast. We went to a place which makes their breakfasts from real food: no pancake batter in the egg dishes like Denny's, IHOP and others. Of course I got no toast. In the past, I would have ordered sourdough or whole wheat, and eaten some, even if I wasn't that hungry. So, I saved those calories.
I don't eat the cakes and goodies brought to events for birthdays and such. So, in that most of us feel better. No question is a stupid one unless it goes unasked. Good luck and hang in there.
