My mind whirrs as soon as I go to bed. Often I fall asleep with the television on, and wake up later to find that my mind will not sleep for talking to me. I walk to the other bathroom, go to a certain shelf, find a bottle of antihistamines and take one, replacing the bottle where it came from. Generally I can fall back to sleep relatively soon after that.
It has occurred to me that someone could change the contents of that bottle, or that they could just change the bottle, but I would recognize the shape in my hand, and the way the bottle closes.
It's a crapshoot, but since it's not a high traffic area, I'm going to go with trust.
I'm already tired.
