Udo, Marc, Eric - thanks for your inputs. I looked up "symptoms of
dehydration" with Google and found this:

Symptoms
* Dry or sticky mouth
* Low or no urine output; concentrated urine appears dark yellow
* Not producing tears
* Sunken eyes
Signs and tests (from a physical exam)
* Low blood pressure
* Blood pressure that drops when you go from lying down to standing
* Rapid heart rate
* Poor skin turgor (pinched skin doesn't spring right back into
position)

Udo, I can sleep for 8 hours without a bathroom visit, but my father
couldn't starting at about 70. Marc, you say "noticably dehydrated" -
what symptoms did you exhibit? Eric, my last bathroom visit before
flight usually produces a goodly amount of pale urine and I don't have
a dry mouth, so I don't think I'm dehydrated before flight.

How about after the flight? If it's still pale, and there is plenty of
it, you might be fine. Still, the same doctors tell me you might not be
aware of the loss in ability, both physical and mental, so I'd suggest
you talk to a soaring physician about it. I know you are reluctant to
give up the convenience of flying without urinating, but 6 hours (!) is
a long time between urinations, and suggests you aren't hydrated enough,
even though you feel fine.
