You may remember that I tried to do polyphasic sleeping a while back, and was sabotaged by my own brain.
It turns out that the writer of one of my favourite web comics has another sleep suggestion for those with flexible schedules.

Make sure you leave your mouse over the comic to read the pop up text.

There are some great web comics out there. My favourite is xkcd, which is strongly targeted at the geekier demographic. But I particularly loved this one, which hit close to home, and explains why my technophobic friends always ask me to come to FutureShop with them.
