Thanks a lot for all your words of wisdom! I really appreciate it. Regarding sushi: I've found that if I get cheap sushi (like the kind in a cafeteria or supermarket), it often makes me feel like crap. So they must be slipping something in there made of gluten. Any idea on what that is and how to avoid it? (Of course, the easy answer is "don't eat cheap sushi," and that works pretty well.)
