The science of sleep

I'm really tired today. Like bleary, feel like I took speed yesterday and spent all night chewing on filters tired. Which is weird. Because I didn't. I had a glass of wine and copulated and watched some silly television, all of which would indicate Sleep Like Baby. But no. Tossing and turning and waking up and watching the sun rise, watching the buildings across the river light up delicately until they became hot gold and left oxidization stains on my eyelids. Almost worth it. But yeah, I'm not going to be very productive, I don't think, today.
