It's not that I can't sleep - it's that I don't want to. Sleep is such a waste of time, after all. There's plenty to do, but in theory it's too late to do it. Even worse, I still have to wake up at the same time, whether I go to bed now, or in an hour, so what's the point? Might as well stay up, catch up on things that haven't been getting done, and reduce the sleep element. There's no real good reason to lay stationary and inert for such a significant time anyway - how horribly inefficient!
Speaking of "Insomnia", the very best song ever with the word Insomnia as the title has to be from Faithless.

Sample lyrics:
Deep in the bosom of the gentle night
Is when I search for the light
Pick up my pen and start to write
I struggle, fight dark forces
In the clear moon light
Without fear... insomnia
I can't get no sleep
