I know I experienced the first of those quoted effects.
Every quarter I do a 1500km drive(or actually 3000km given that I drive back and forth), which is now split into two days, but that wasn't always the case - I used to regularly spend 20h+ driving.
Anyway one thing I learned from this is how to recognize if you're likely to fall asleep at the wheel soon: you get cold, even if you weren't before.
