Patty and I went for our short walk. It turned out to be even shorter than we had planned -- about 15 minutes in total. Patty's nausea and fatigue came roaring back, so we abbreviated our route. We had to stop mid-route for Patty to catch her breath. We passed a woman who had marveled months ago about our rollerblading excursions...and wondered what might be going through her mind as Patty shuffled along with tubes all around her.
Patty described her current state as "like a baby" -- short periods of wakefulness amid many hours of sleep. Five minutes after our walk, she was fast asleep. I'm really getting worried. More later...
