I spent large portions of the night in the bathroom and got light-headed enough I was using the walker. No more sushi from Taste of Asia! I called Kaiser Advice because their book says to start with just water and then go to Gatorade and I wondered if I should start with the rehydration fluid. I got a long interview to make sure I hadn't had a stroke, and in the end, the nurse reported that the doctor said to drink more fluids. So I had more rehydration fluid. There's a good chance I'll be napping soon.
