The only real 'horror' story I have about not eating, wasn't even the fact that I didn't eat. It's that, I know I can't eat until after at least two hours of being awake at a con. And I ate breakfast, 30 minutes after getting up. I ended up throwing it all back up right before getting to the convention center. ): It wasn't pleasant.
Otherwise, I'm generally the one in my group that says "Hey I'm hungry, lets go eat. Because I know you guys aren't keeping up with your hunger." Depending on the con we're at will determine what we eat, since we don't bring our own food. But, it's something to keep us going. (Even if it's as gross as McDonalds. I always end up regretting eating it when I do. But it's cheap, and it doesn't involve me crossing an 8 lane road.)
Next con: Anime Mid-Atlantic
