Personally, I've had the opposite problem from most people; it takes a lot of willpower to eat regularly.

I have sort of the same problem. I was on a diet for a really long time (wrestled through grade school and high school), and to this day, I get full really quickly. Two of my friends (neither can weigh more than 105lbs) get really pissed at me whenever we go out to eat. They end up finishing their meal, and I can never eat more than 1/2 of mine, especially if we get an appetizer. I guess it makes them feel like they are fat :/

One of them makes sure she calls me on weekends, even if she is out of town to make sure I eat something, otherwise I will just forget.
