Well...

I most definitely don't have a hangover. I didn't drink, smoke or snort anything yesterday, so I should feel like a hundred bucks, right? WRONG! Here's a good recipe: Stay awake for 30h straight, right in the end of the stint go and do some snow-work (if you don't have snow you can replace this with any menial but physically demanding job). After that fall asleep on the couch for an hour and a half. I guarantee you that when you wake up you feel like you've been hit by a freight train...

Totally worth it though :)
