Haha, I know that feeling all too well, FEISAR. I should have gone to bed early last night, but instead I decided that playing speed lap on Pulse would be a better idea (after not bothering to play Pulse for ages due to laziness XD), and as a result, had to operate machinery today while fighting the urge to fall asleep.
As long as you don't make a habit of it and don't do it when you have something very important the next day, it's not too bad though.

edit: Megavideo... yes, OBH.
I always try to remember to reset my router before loading a video on there, because it also resets my IP address and the limit for Megavideo.
