Over the past half day or so I have managed nine and half hours of sleep, including waking twice on my wound side. (Ouch.) Also, finally the gates of my lower GI have properly opened, which is a relief so profound it cannot be described, and a cliché so worn that someone who's never been in the position of needing that relief tends to find it laughable. (I was similarly blissfully uninformed and tactless in my youth).
Another day of laying low. Things do hurt a bit less.
