Sleeping

I'm prone to insomnia. I'm not sure if it's because my natural bio-rhythm is to be awake all night or due to too many thoughts in my head. This week has been a bad one for sleeplessness. Tuesday night I saw 4 am and last night I was still wide awake at 2:30 am. No wonder my head feels like it is full of cotton batting today.

This doesn't lead to much in the way of productivity. It also means my mind tends to wander a great deal more.

Could creativity be tied to sleep deprivation?
