I was feeling tired the middle of the afternoon yesterday, so I took a nap with Emily. Later we went out for dinner and I was feeling increasingly uncomfortable on the way back home. I went straight to bed and next time I woke up, I had a fever developing. It peaked at 38.7C (101.6F) in the middle of the night. By morning it had thankfully subsided. Now I have no fever but still achy. Hopefully that was the end of it, because I need to fly to the US tomorrow.
