Here's his technique: pick a letter of the alphabet, and find as much words that start with this letter as you can. Once you can't find words anymore, pick the next letter. Doesn't work for me, my brain won't ever stop.
I noticed I have to visualize stuff in my head to fall asleep so my adaptation is to pick a single letter and a single word, and visualize it in my head, using it, manipulating it, experiencing it, whatever. For example: letter P, word Pineapple, imagine you're holding a pineapple, you feel the roughness of it's skin in your hands, you throw it in the air and catch it again, you take a knife and slice it on a wooden table on the beach, etc.. The dream kicks in seconds. Without external interruptions, after a few minutes I'm asleep (instead of rummaging for hours).
If you notice you're stuck in a loop/pattern (for me anything about text, like reading or writing, and voice, like listening and speaking, or stressful scenarios), just pick a new letter, pick a new word, visualize it.
Another thing I do that works well for me is just counting breaths. On the breath in I think "in-n-n-n-n" and on the breath out I count. When I lose count, and I am still awake, I start again from 0, as any sane programmer would ;-).
ETA: For a couple of months I have been doing a short gratitude routine as I am getting into bed. I acknowledge the good and positive things that happened during the day, and I tell myself that I did a good job (if I did) or that I did as well as I could today and that's good enough for today. Then I think, "And now it's time for rest. I've been looking forward to this." If any part of me starts thinking about the day again or thinks about tomorrow, I gently reassure it that I will attend to all of this tomorrow morning and that now it's quiet time and time to rest.
All of this plus 250 mg of magnesium an hour before bed has made falling asleep super consistent and easy.
- think of past enjoyable moments (for me it's hiking, I usually don't go very far until I fall to sleep)
- box breathing
- hold breath for N sec then release, then N+10, then ...
- try to relax your body from top to bottom (forehead, eyes, cheeks, mouth, ...)
- imagine your body is very light, like your floating in the air
- imagine your body is very heavy, like a block of concrete sinking into your bed
- pick TAOCP and try to solve the exercises ;)
May sound like a lot, but I sleep now.
Who needs the exception of e-ink screens are OK?
The routine is basically a game to see if you can "flow" between mental images by envisioning scenes in your mind and then allowing some object in the scene to "pull" you into a different scene. For example, envision the power cable of your lamp, you fly along the power cable up to the light bulb, and then you envision the bulb glass exploding into a million pieces, which becomes snow falling on a ski lodge, you see the warm glow of fire in the fireplace, and a fireball blasts out the chimney into the sky, somehow becomes a perfect flaming sphere, that becomes a meatball and falls into a plate of spaghetti, you are eating it down, you see yourself at a ratty diner table, under the table you see your shoes, and then your shoes are running through rain puddles, you zoom into a single droplet which is actually a massive aquarium tank, fish are swimming in it except we are in the ocean, not a tank, and the fish is so colorful but those colors are actually an explosion of rainbow paint colors dripping down an apartment wall, etc. etc.
It might sound ridiculous when written in words, but that is the gist of it. The game is to lay there and consciously morph and fly between mental images, letting your mind conjure imagery that comes next.
It's crazy because I start doing this with a conscious struggle to envision the next chain-of-events but suddenly my brain catches on and starts unconsciously playing the game and images just kinda flow and BAM asleep.
If I lie in bed and just think stuff, it takes much longer.
Not sure if any other buds work like this but the Bose QuietComfort Earbuds seem to auto-pause based on some kind of fitbit/sleep indicator which help even more with staying asleep.
One thing I've done for years is focus on breathing. Get in a comfortable position and totally relax your body. Slowly take a deep breath. Then exhale until you can't no more. Repeat this 10 or 15 times.
For whatever reason, this works for me probably 75% of the time. The other 25%, forget it.
On a side note, I'm sure most of us here can relate to this song. https://youtu.be/vaG4vGsIFMQ
I buy 1 mg tablets and even that is too much for me. I use a razor blade to cut them into 1/6th pieces.
Takes less than 30 minutes to kick in.
A lot of other comments here about poor sleep I believe are the result of drinking caffeinated products past 1 PM.
Huh, mine is a plane in level flight. (From outside.) Preferably smaller. Depending on my mood it’s retro or like a fighter jet.
