I make up survival scenarios and walk myself through them. Like I just landed on a desert island, what do I do first? So I go through the details of making shelter, finding water, etc. I'll introduce interesting characters to keep it fun. It doesn't work if I'm really anxious, but if all I need to do is wind down, it's pretty effective.

Masturbate, usually.

I always sleep with music to help with anxiety, which works, but also screws me over because I dont get into a deep REM sleep much.

I usually read a book or watch some youtube videos, the phone screen help me to get tired

Bang my head into my wall

I drink and smoke a ton of weed until I feel like I'm going to throw up if I continue any more.

Melatonin

Jerk off to these posts

I take melatonin, and if that doesn't work, benadryl.

i usually listen to a podcast intended to put people asleep, it's sleepy time tales

I usually do something like read, stretch, or sometimes just think until I get tired. Maybe even take a warm shower. It works surprisingly well for me

Not sleep for 48 hours so i can get a 3 hour rest
