What I don't think I've ever had is what I had yesterday, where I had breakfast, cleaned up around the house, took a nice long walk, showered, had lunch - and then pretty much passed out.
No, seriously. Barely made it upstairs, was half asleep by the time I reached my bed, and then I was unconscious (for the most part) until sunset. My body was like "screw this, catching up all at once."
(I did have one period of time where my brain was awake but my body couldn't move. Not sure how long it lasted.)
So yeah, I have energy today. I'm cool with this.
I'm not cool with not getting any writing time yesterday! But I will persevere, and will write after today's walk. If I don't pass out again. Please let that be done with, body. Kinda freaky.
