On the one hand, this isn't a huge deal, since my earliest in person class in the fall is at 1pm, but on the other, I'd like to know why this happened all of a sudden. Hmph.
[edited to add, "this is why I LJ" version: Clicked on my sleep tag, and the next entry down is an entry from last August about how I'd slipped to a 1am to 9am sleep schedule at the end of the summer. Guess this isn't so all of a sudden after all. :)]
