             | The primary benefit from mid-day naps is that they simply
             | help you relax and get some rest. You don't want them to be
             | long, just refreshing. This is well known in athletics
             | where most major athletes take naps as a matter of recovery
             | and to improve their sleep quality. Presumably, feeling
             | relaxed and rested when you go to sleep helps you get some
             | deeper sleep and improve sleep quality.

           | get to sleep:
           | 
           | - No exercise after 18:30/6:30pm
           | 
           | - Absolutely avoid Vitamin D and Vitamin B supplements in the
           | evening. These will suppress deep and REM sleep and I'll
           | sleep lightly all night long if I take them.
           | 
           | - Hot sauna, shower, or bath before bed.
           | 
           | - Anti-histamine (cetirizine hydrochloride aka Zyrtec) as
           | needed - I'm allergic to my wife's dog and some nights I feel
           | like I have bugs crawling on my skin. It can even wake me up.
           | 
           | Things that keep me from waking up at night:
           | 
           | - Gas X as needed to avoid acid reflux
           | 
           | - Anti Inflammatory helps keep me from having to use the
           | bathroom when I know I'm inflamed (getting old sucks).
           | 
           | - No alcohol in the evening
           | 
           | - No videogames, interesting books, or French lessons right
           | before bed, or I'll be sleeping lightly and find myself
           | ruminating in light sleep over these mentally engaging
           | topics.

             | A couple of tricks I use with these:
             | 
             | - I cut about 1/4" off the small end. If I don't, the
             | earplug starts to hurt my ear if I wear it a lot, I think
             | because it goes too far into my ear.
             | 
             | - before using a new earplug, I wash it several times with
             | bar soap. There is something in a new ear plug that makes
             | it stay mashed. Maybe it suppresses more noise with that,
             | but it also makes it hard to fit for me. I keep washing it
             | until it is springy. This is a one-time thing with a new
             | ear plug.

       | I have some unconventional sleep tips for those interested.
       | 
       | DURPLEDRANK'S GUIDE TO BETTER SLEEP:                   Line your
       | sleeping room with books. They are an inexpensive way to
       | soundproof your room. If you have noisy neighbors upstairs,
       | you'll "hear" them, but more importantly, you won't "feel" it.
       | Use comfortable earplugs and a baggy winter hat as a sleep mask.
       | Sleep masks can be uncomfortable, so this is a great alternative.
       | Play a BROWNIAN NOISE loop on speakers in your room. You can
       | easily generate this in Audacity with a few mouse clicks.
       | Take antacids before bed. Many sleep problems are linked to acid
       | reflux. Drinking carbonated water or water with baking soda can
       | make you feel tired instantly. For any scientists out there,
       | please credit me for this discovery. If you have acid reflux,
       | your brain won't let you sleep.              Stay warm. Being
       | warm often makes you sleepy, although the reason isn't clear.
       | Use red lights in your sleep room to avoid blue light. Replace
       | your reading lamp with a red light to help your brain switch into
       | sleep mode.              Limit screen time. Dim the brightness
       | and enable blue light blocking mode on your devices. Older
       | devices may be less disruptive to sleep than modern ones.
       | Keep a notepad for quick Google searches. Whenever you have a
       | random thought, jot it down on a to-do list to avoid grabbing
       | your device. This helps you stay off screens.
       | Consider taking 1g of melatonin, but note that it may not be very
       | effective if you have acid reflux.              Elevate your
       | sleeping position to combat acid reflux. Even if you don't feel
       | it, you might have some built-up reflux if you burp or fart after
       | drinking carbonated water.              Invest in blackout
       | curtains.              Cover every blinking light or power LED in
       | your room with electrical tape to create a pitch-black
       | environment.
       | 
       | TL;DR: In my journey to fix my sleep, the most critical factors
       | are 1) managing acid reflux, 2) soundproofing and reducing light
       | in the room, and 3) using red light.

         | wake up early enough that you can just go for a 15-20m walk
         | with no destination and wake up your body.
         | 
         | - No screens past 6pm or so. I allow my watch, but I hide my
         | phone. I will let it ruin my sleep over and over and over. I'm
         | only a hairless ape, and I need to plan to prevent myself from

         | the time or weather/etc. But I need to keep the phone far away.
         | 
         | Different things work for different people, and maybe you're
         | already pretty close to something like this anyway. I only
         | mention it because I started with magnesium threonate too, and
