One slice bread, one tablespoon peanut butter, cocoa pebbles

That's all I've had to eat since Friday morning that has stayed down. Actually, I just had two butter cookies that are doing okay. How come when you can't eat right you feel so bad? I definitely have enough pudge stored up to feed my bod for a few days. I don't get it. Why wouldn't the body metabolize fat to fight feelings of dizziness? (Not a rehtorical question, I really am wondering)
