How awful. I didn't get this too much, but I know that pretty much every opportunity, it's good to get your feet up. Is there ANY position where it's comfy to have feet elevated? Can you lie on your side on the couch with your feet on a cushion and watch your daughter play from there?

You poor thing. Facewashers or handtowels with icy water around your ankles? If you can't get water down, maybe drink a sports drink or hydralite or whatever it's called, to make what you DO drink really count?
