My sleep is like blink of an eye. It's night, I close my eyes, then I open them, and there is morning already. I's always the same, no matter how long I have slept, whether I am well rested or tired.
Since the time feels so compressed during my sleep, I can't help but feel that sleep is, kinda, a waste of time.
Usually I have 2-3 coffees per week. I drink a lot of various types of tea daily, though.
