Electra -- I've found that when I am pregnant, I get extremely hungry, but if I eat a huge meal, it knocks me out for the rest of the day. The key is the large size of the meal. If instead I have several smaller meals, then I don't get hit with the gigantic sleepies in the same way. I don't think this is gluten-related, since it happens to me even on a gluten-free diet. I don't know if this is what is happening to you, but I figured I'd mention it, just in case.
