Hangover

A feeling of hunger, but you don't want to eat.
A feeling of being able to conquer the world, but not being able to move off the couch.
You'll have a headache, you'll stumble when you try to stand, and you'll really only want to eat at your favorite small town diner.
You'll belch and have the taste of your last drink in your mouth from the night before.

I'm not up for a run I've got a hangover
