I talked to my mom this morning; I don't know that she's feeling better, but at least she's not dehydrated anymore. She's just bored and lonely--it's a suburban hospital on a long holiday weekend, so they can't even do any of the tests her doctors wanted to run.
If I were nearby, I'd bring her a portable dvd player and a stack of movies. Well, at least she can read: I hope she has enough books!
