When I stay up all night, by morning I can taste the deprivation in my mouth... it tastes poisonous.
Also I too have gotten sleep paralysis once in a while, but not in the last year or so for some reason. Usually it was that I would wake up but I couldn't move any muscles, not even open my eyes, and after what was probably only a few seconds but felt much much longer because it's kind of terrifying, I would be able to force my arm to move a tiny bit and then regain control of my body.
