What is the sign that you've stayed up too late?

[Sarah3]

When I wake up too late the next morning, or weird enough, when I have trouble falling asleep.

When I check the time and it’s 3 AM (unless if I went to bed earlier and wake up then).

When the sun starts rising!

I don’t have as many of those nights, actually. But in my training, I did have a fair number of overnight shifts, or extended shifts. So I made the most of it and would go out for breakfast afterwards!

My body is pretty good about telling me when it needs sleep; I could almost nod off anywhere. Usually this ends up being around 10pm; I call 10-11pm my witching hour, because over the last decade I’ve gotten so used to having to wake up really early for work that 10pm is usually when my body needs sleep. But if I make it past that, then I usually find a second wind!

2 AM onwards on rare occasions when the sun is starting to rise i just err. accept my fate

I get acid reflux. Interestingly, there are researches that confirm that these two are related.

the only way i can tell is if i can see the sun rising! my body has kind of just accepted that i can’t/won’t sleep sometimes
