Much better.

This morning, I felt too weak and shaky to finish an entire cup of tea. (I tried. Twice.) When I moved, I felt dizzy - I kept having to suddenly sit and put my head down.

I slept most of the day, in between failing to follow things on TV and craving increasingly larger snacks. (Canned pears, crackers, chicken soup - I was a real culinary wild woman.)

Tonight, I feel okay. Tired, but okay. I ate a normal - albeit pre-selected for blandness - dinner. I carried on reasonable conversation. I stayed awake through multiple episodes of Buffy on DVD.

Looks like a 24 hour bug. Thank you all for your good wishes.
