I did not feel at all well this morning, but was able to drag myself to the office and work from 6:30 to a little after 2 PM, when I went back to the hotel, where I'd hoped to be able to lie down. However, I did check my mail, and sure enough there was an issue that needed my immediate attention. In the end, I worked more than a full 8 hour day including troubleshooting that issue. Oh, well, that's why they issued me a smartphone. (And indeed, with the hotel's wi-fi so wonky here, I had to use the smartphone's internet bridge to actually pull the files I needed.)
Oddly enough, I don't feel as sick now as I did this afternoon. Maybe I'm getting over this low-grade cold that hit me over the weekend.
