Thanks and good point.
I fell asleep around 7 am (21 hours or thereabouts of being up), slept two hours and then got up at 9 am for classes. I've been awake since then because I had stuff to do between classes.
Giving my capstone course presentation on two hours sleep was an interesting experience, but I still did well on it even though my eyes are bloodshot enough that I look high.
I might nap for a couple hours before Heroes or do what would be smarter and just stay up until Heroes is over and then crash.
