Sleep deprived

This has not happened to me in a while. 

I stayed up until 7am yesterday. 
Not deliberately. My mind was just awake and thinking. 

No rain sounds, no meditation, no audiobooks would quiet it down. 

Earlier in the day - way before noon, I drank a few drops of coffee with a lot of almond milk. That was the only new variable that I could think of. But to keep me up until 7am, that is bizarre. 

I got a few hours in the morning but my body and Oura told me that I was not going to be great today. My mood was off. I was tired. And couldn't play chess the way I usually do.

So I am going to sleep early today. 
Tomorrow, it will all go back to normal.
