Sleepless night...

I lie here as many sleepless hours go by.

One o'clock rolls by,
I'm not too worried,
I can still get up in time,
One hour and counting.

Two o'clock comes and goes,
I give up a little bit,
Play on my computer,
Second hour's gone.

Three in the morning,
Normally people aren't up,
I'm still trying though,
Now that's three hours!

Four o'clock and beyond,
I don't know how it happens,
It's amazing!
This is usually when I fall asleep.

Where do all these hours go?
The answer is nobody knows!

I lie here as many sleepless hours go by.
