Thanks for the ideas. I've always been intrigued by the siesta culture -- up early, nap during the heat of the day, and long long dinners after 9:00 p.m.

I usually do take a brief nap around 4:00. This time, though, it was as though the day were one long nap with brief periods of consciousness.

Thanks for the tip on calcium -- I didn't know that. I thought you had to take it with meals.
