Sleep is important

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."

That part about being afraid youll oversleep is also anxiety.
Anxiety prevents sleep, general advice is to have a routine that calms you down.
My thing is just somehow convincing myself theres nothing to be anxious about. It really helps though if you can handle whatever might happen as a result.
Last time I couldn't sleep like that it was because I had sentencing in the morning and I didnt think I could handle prison. Luckily I didnt have to go.
- My problem is that when I don't get enough sleep I just sleep through my alarm. It's definitely anxiety but this one is based in reality, unfortunately. I've made that mistake a few times...

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

Great way at looking at it. You might not be asleep, but you're still laying down getting some well-deserved rest.

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

I love falling asleep 1-2 hours after getting in bed and then waking up an hour before my alarm 🙃. I can't help much I can relate!
L-theanine and cannabis indica. Throw in some DPH (Benadryl) if you still can't sleep.

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.

Its good advice, but a razor thin line to walk. Takes a lot of practice IMO to do it right.
- It's* good advice

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

2 - 4 beers and 0.5 - 2mg alprazolam usually calms me down enough that I can get a handfull of hours of good shuteye.

Thats practically putting yourself to sleep, besides the fact mixing those two substances is absurdly dangerous.
Good luck with all that but its fucking awful advice.
Or 200-400mg of L-theanine and a couple of dabs of a heavy indica if you don't want to risk turning that sleep into an eternal one.
As fun as the beer and benzo combo is, you should never mix the two. Ask me how I know.
- how do you know?
"good" lmao
Can attest that it works great, except for the dogshit sleep quality, like with almost every sleep aid known to man. (except for GHB and Pregabalin, but these have their own issues)
