Sleep was eventually had.
Not enough of it and it had to be while I was lying on my side. Still an improvement over only being able to think of sleep if I was sitting upright and leaning forward a bit.
I have a lovely husband who came to sit on the couch and stroked my back and let me be feeble and teary and whingy at 2am when it had become all too much. Spot the girl who hates being sick and doesn't deal well with no sleep.
Hoorah! for lovely husbands.
