When you are up so late or get so little sleep that you have the same symptoms as if you had been out at a bar/party pounding down the drinks... headache, stomachache, hungry, everything is loud, etc.
Man, I was at that party last night and didn't have a drink ... but was out so late I'm sleep hungover!
