The linked article doesn't mention tolerance at all? I don't believe there is any evidence out there to suggest that melatonin tolerance is a thing.

You're right! Edited the post...thanks for pointing this out was actually a mistake on my part the article was about incorrect dosage which was the point I wanted to make.

Ahh then yes that's a super valid point. I've seen shops sell 10mg per tablet. 0.5mg already does the trick for me.

Melatonin has helped, of course. But a few other steps I had read on a Reddit thread [0] also helped me - specifically the point about relaxing facial muscles. For some reason, doing this also seems to calm the mind and reduce random thoughts. [0]: https://old.reddit.com/r/sleep/comments/1bn2emp/how_do_yall_...

It is crazy how you can relax your face 4-5 times in a row getting less tense each time, and how well this method works to get you to sleep, especially after it has worked for a while so your body associates the relaxing with sleeping.

I wonder how much of sleep research is affected by the difference in sleep quality between your own bed and a lab. Even if you're on vacation and the hotel bed is of exceptional quality, your brain knows that it's in a different environment and would naturally be on partial alert, at least for the first couple of nights.

Now imagine sleeping in a lab setting, knowing that your sleep data is being measured. Intellectually you know that you're not at any risk but there must be some difference in the architecture of your sleep.

I started intermittent fasting and my sleep improved remarkably when I stopped eating calories after 3PM. Last night it shows I was awake for 16 minutes but in the morning my dream memories seem to be vast.

My mother got Alzheimer's in her early 60s and was always a super light sleeper despite a healthy and happy lifestyle. I suspect her brain's glymphatic system wasn't kicking in often enough to clean her brain.

Sounds trite but my surefire method is to stop thinking. I literally lie down, close my eyes, and stop thinking. Sleep comes quickly.

My mom always told me to do this as a child. I’ve never understood this nor any other visualization technique. I have never found this to be possible. At best I actively think about not thinking which is counterproductive but even then within about 10 seconds my mind has already wandered. And if I’m not actively trying I’ll always have some other thoughts popping in no matter what

It might be because it wasn’t a technique as such. I don’t visualise not thinking, I just stop thinking about things, but I also don’t have a constant inner voice talking to/with me as I understand many people do.

Taking melatonin has been mentioned several times in different threads here, and I just wanted to add my experience... I find that taking the minimal amount make a big difference here, and it's about 3 micro-grams (not milli-grams) for me. The trick is to get some liquid melatonin drops. There is a brand that has 3 milligrams per 30 drops as a recommended dosage, so I just take 3 or so drops and let them dissolve on…

You emphasized the word "minimal" but it cannot be emphasized enough. I think melatonin is one of those things that quickly backfires if you take too much.

You might know this, but sleep debt doesn't just keep piling on. Eventually, and rather quickly, you may begin to experience permanent brain damage after a few nights of sleep deprivation. https://www.ahajournals.org/doi/10.1161/STR.0000000000000453 From one insomniac to another... In the past I've been lucky if I get 3 hours total of sleep in a night due to physical pain disorders. I have deep trouble getting into N…

When you say “sleep medication” what do you mean specifically? AFAIK melatonin is safe but diphenhydramine overuse is linked to dementia.

I'm still exploring my options, open to suggestions. Medications like zolpidem and diphenhydramine are definitely off the table.

I find that Yoga Nidra helps a lot. It relaxes all your muscles and also has nothing to do with "yoga".

Two things: 1. Too much deep sleep might not be desirable. 2. Sleep staging by activity trackers is generally pretty inaccurate. Garmin is no exception.

Could you please elaborate on 1. ?

Personally, I am very alert throughout the day if I sleep between 6-7 hours. Past the 7 hours threshold I am get into a worse headspace (brainfog) throughout the day proportionally to the amount of extera sleep.
