I'm still working on my answer, but I was sharing this with my daughter, and she made the observation that by noon you would have likely had input only from the morning people...or if you had input from people who were worse in the morning, your data would be slanted because of that.

She was just being a smart aleck (where does she GET that?) but I was thinking she wasn't far off. If I wait and answer in the morning, you might get a well thought out, articulate answer. If I answer in a couple of hours, you'll probably get "bite me". Know what I mean?

The cognitive part was easy: I start out reasonably sharp once I get the cobbies out of my head, and get progressively worse as the day goes on until I hit the Dead Zone, between 5 or 6 and bedtime, when I essentially just take up space.

Physically I am horrible from the time I wake up and realize I'm still alive until the naproxen kicks in and I get myself pulled together. Say an hour or two. Then I am "okay" until the end of the day when I get worse again and can barely drag my fat self around.
