Fall asleep at your desk.
Donno about you, but it works for me.
I can't sleep at night either, the second my head hits the pillow my mind bursts into activity relieving things that have happened up to 10 years ago.
But, as long as my head don't hit the pillow...I can sleep.
So just get a comfy keyboard :p
