I'll pass. Why should I take a drug that will cost me money, force me to see a doctor, probably give me side effects, and may even cause real harm (anybody remember the hormone replacement therapy all the doctors wanted us on?), when I can stick to a gluten-free diet for free and with no harmful effects?
I think I'd try it because I find it difficult to eat gluten free everywhere, travel, out for an evening, etc. I simply miss bread. I hate to be such a weenie, but for me, there's nothing like real bread. If the testing goes well, I'll be in line to try the drug.
