One time, we took my celiac mom to the country club for dinner because the chef graciously accommodated her needs. But, the waiter accidentally placed crutons on the salad. I intervened, removed the crutons, and she proceeded to eat the salad.

Of course, there were tiny crumbs and mom was immediately sick.

I hate what you're going through and I hope it will get easier. But I also saw the difference for my mom once she regulated her diet.

Have you checked for the chain restaurants that have gluten free menus? In Evansville, we even have an italian restaurant that offers gluton free pasta!
