Do you ever get hungry for no reason even if you just not too long ago (say, within 4 hours)? I have had this happen for the last week or so, and can't stand it! I drink water, but that still doesn't help! I know it is a mental thing, though. Because if I don't think about it, it goes away. I always thought it was my metabolism speeding up, burning the food off quickly, but I don't think that is really true!
