I spent a few months living in a rainforest. We slept in hammocks, and
it was a significant hassle to get up in the night and relieve oneself.
At the end of each day we were typically a little dehydrated from the
day's exertions. The method I used to get hydrated but not need to go
for the 8 hours of night was as follows:

Drink A LOT of water between around 4pm and 5pm - more than I wanted
to. Then sip very small amounts for the next 4 hours. I found I needed
to relieve myself quite a few times for the first 2-3 hours, then less
and less so. Then go to bed. I reliably did not need to get up in the
night. No doubt the physiology is different for night vs day, but I'm
betting the same method would work for flying (although I haven't tried
it).

As some people have said, you need to avoid diuretics like caffeine.

I've got a four-cup coffee pot that makes two mugs of coffee. It's
theoretically four six-ounce cups, but it's actually closer to five ounces
each. I tried pouring water in from a measuring cup instead of using the
pot one time, and it went all over the counter.
