I came home by bus yesterday morning, leaving my bike at work (with the removable valuables stashed under my desk). Over the weekend I'd developed a cough, with a small but painful stab in the middle of my chest. That expanded to a real thumper of a headache and a lack of energy, and I slept for 3 hours in the afternoon. I felt better over dinner time, then faded again in the evening.
Today it's become a nasty taste in the back of my throat and sinuses, and I'm even more listless, so it's home again for me. Now I'm hoping for it to develop rapidly into a full-blown cold, so I can have a yucky week then get over it.
