The good news is, I've gotten almost 12 hours of sleep in the last 18.
The bad news is, of course, I'd rather be exploring Bend, not passed out in my hotel room clutching my stomach.
It's not alcohol; I had precisely one beer with dinner and one glass of local wine after. And I went to sleep at my usual time (11pm CT/9pm PT). But when I woke up this morning, I felt a general malaise that became, after a bagel and coffee plus a one-hour walk around town, light-headedness, nausea, and unbelievable fatigue.
I'm now going over in my head everything I've consumed in the last 24 hours and I have a suspect. Still, it doesn't feel like food poisoning exactly, so I'm not entirely sure what's going on.
I feel better now after a 3-hour nap. Making my goal of 25,000 steps seems highly unlikely, but I can still get in another 10k or so before collapsing completely.
Bonus: here's the Mirror Pond, just a few blocks from where I'm staying.
