I know what you mean, I got careless and instead of picking up the Udis gluten free bread I grabbed a loaf of Rudis (not gluten-free) bread. I ate about half the loaf when I realized what I had done, I was out of town at the time and it took just a little while for the drowsy, stumbling symptoms. Then a migraine that started the morning I was supposed to take a 4 hour flight, although I take Imitrex, it takes a while to kick in, and one of the things I cannot do with my headaches is sit or lay down, not possible on a plane. Poor fellow I was wedged in with on the plane, I probably looked like I was gonna die - I felt like it!
Why can't stores make up gluten free sections instead of mixing organic and gluten free together. And lord only knows why Rudis and Udis have to look so much alike.
