The Tiredness Phase

For some reason I was REALLY, REALLY tired this evening. I was fine all day but around 11:45 I felt completely drained. So much so that I eventually ended up laying down for about a half hour. When I got back up I felt even more tired and if hadn't been for the fact I wanted to watch some TV at 1, I might have even gone to bed. And now it's almost 3 AM and there's not a trace of tiredness to be had. Whee!
