Leaden sky prevented light from reaching my window. I didn't wake till five o'clock this evening. My schedule has thus reached the point of total breakage. It will be necessary to find a way to restore it to something closer to normal. This is something I haven't had to do in almost three decades. If it is not done, the instability will grow worse. I don't intend to resort to any sort of medication. But it probably means that I'll be here at even odder than usual hours for a while, and will probably have to limit my computer use as a result of everything else being in flux. Rats!
