Being sick. Specifically the kind that results in a painfully sore throat. Case in point, my throat feels like it's covered in sandpaper, it hurts to swallow my own saliva and I'm starting to get really fucking hungry. I know I'm probably going to have to eat by the end of the day, or perhaps tomorrow morning at the very latest, and yet I know it's going to feel like taking a belt sander to the inside of my own throat.
I get the feeling this would be really handy if I were dieting right now. As it stand now, though, it's really not.
