Some people say they don't get much sleep, either because there are other interesting things that keep them awake (so they stay awake until their body tells them they need to sleep,) or they just don't have the luxury of sleep. Or if you were like me, your sleep cycle makes it hard to sleep.
I ABSOLUTELY love sleep, but if I had the chance, I would stay up if I could. Something about having naturally low energy and wanting to get all the sleep I can get.... besides the fact my circadian rhythm is out of whack and I consciously start feeling sleepy at 6 a.m for no good reason (whether I went to sleep or not.) I've tried every method I could to get my body to recognize that I want to try to get to sleep between 9pm to 12am, nothing seems to work lol. So the chemicals that tell me I should sleep starts reacting at 6am.
So I don't know...maybe staying up more often is a good thing for me.
