Brian again. I spoke to Mom about an hour ago and she sounded pretty good. The docs seem to be getting a handle on her electrolyte chemistry, etc. Nurse Sis is doing heroic work looking out for her well-being. I asked Mom what she wanted to publish in her blog and she said this:
"I'm starting to feel like my old self again. You could say that I think I've turned a corner, except every time I turn a corner I just run into a new road with more potholes in it."
That sounds like Mom.
