Stayed up all night, browsing the net and such (mostly DV, of course).

Now what do I do? I heard about REM rebound but never fully understood it as it didn't apply to me as I usually slept during the night. I have been up since 11am saturday and it is now 8:40am sunday.

When should I go to sleep? Should I nap? How can I best use this situation to get an LD?
I'm feeling pretty tired, if I shut my eyes and curled up in bed I would definitely fall asleep in minutes.
