Every time I've ever had a big test, a presentation, a job interview, the first day on a job, a meeting, a doctors appointment, a big trip the next day, and literally everything else you can think of, I have stayed up all night. At first it's an issue of anxiety, but by 3 AM it turns into "well if I fall asleep now I can't trust myself to get up in the morning so I might as well stay up all night."

Here's my trick. I tell myself that lying here not-sleeping is second best to sleeping. That calms me down.

Currently dealing with this over the span of multiple days. I'm dying send help.

Here's a pro tip: sleep a lot the day before, and ideally the day before that too. On the important night don't exhaust yourself with gaming or whatever, but don't force it. You'll end up sleeping maybe 4h, but if you slept well the previous two days, you'll be fine.

Sleep deprivation only really shows over prolonged periods of time. You can ace a lot of tests with the above method.

Walk around like you're the king, it's just another day, and nothing can go wrong (nothing that really matters) and you'll sleep like a baby.

These aren't the chill vibes I'm looking for next
