Sleep, unlike drinking, is highly overrated.
I was once up for five days... substance free insomnia. No kidding. Don't try that at home, though.

P.S. That's why I laugh at rookies who think they can challenge me to a drinking contest. I always make it for money, if they persist after I laugh at them.. you can't outdrink somebody who can take a handful of tranqs, drink a fifth and then stay up for two days.
