09:10 – I’m back at my desk, but still not hitting on all cylinders. I’ve had severe nausea since Monday evening, although it’s starting to taper off now. Between then and this morning, I drank a total of about half a liter of water, in sips, mostly overnight last night. Trying to drink more than that made my stomach rebel. I’ve managed to drink half a liter of hot tea this morning, and will try to do more later. My usual daily fluid intake is 2.5 to 4 liters, so I’m way down.
