In my experience, drinking the night before doesn't help my morning hydration levels - it simply guarantees more than my usual middle-of-the-night bathroom visits.

I always eat breakfast before my morning rides - and I do drink water with my breakfast. Then I make sure to drink a lot as I ride. I remember many years ago hearing the recommendation of drinking a full water bottle every hour of the ride. Is it possible that your issues were more tied to not drinking enough during your ride?
