Used to be able to set a clock by my sleep schedule (although it was kind of strange, my being retired and homebound).
THAT lasted forever, until a Rx change now that I think about it. Cut my issue in half, practically in two months.
However anyway, lately I'm finding a good five hours of sleep in a row to be a joke, I know that part of it is actual SORENESS but (shrug).
It's just different this time, not always after having had a fall on my head on the concrete of the patio or the garage. Don't know exactly how else to describe it.
