Exhausted

I am exhausted. This is at least two days in a row. I didn't go to Sangha last night because I just wanted to go home and go to bed. I could no longer focus on anything. And it's the same today. I tried to get a nap at noon but I was in my car — a black car in the sun, which meant I was baking. I don't know if I dozed or not. But it's as if I really have to have a nap during the day, more or less regardless how much sleep I get at night or how much coffee I drink. (I'm going to have trouble giving it all up on Friday for my flight on Sunday.) Or is it the coffee itself that is making me so tired? Sounds counterintuitive, but I've wondered about that before. In general it seems like the times of my life when I drink a lot of coffee are the times I have the most trouble with feeling exhausted. Maybe there's a connection.

Or maybe I'm just imagining the link. I guess that's always possible.
