How come if I go to sleep after drinking, I wake up with cotton mouth and other symptoms, but if I just stayed awake none of that happens? Even if I don’t drink water or electrolytes during the time I’m awake.
Is it just a case of the body slowly adapting while awake vs. kind of “shocked” between two states when I sleep and wake up?

It’s not just one thing. Alcohol dehydrates you, hence the cotton mouth, your blood sugar levels drop, hence the tiredness and desire for stodgy food and, whilst you fall asleep quickly you don’t sleep well (I think your body releases adrenaline to help break down the booze) so you wake up still tired.
All of the above is a hangover
