I suffer from this too (only formally diagnosed with sleep apnea though) and found that 0.5mg of melatonin about 20-40mins before I want to go to sleep has helped me align my sleep cycle to a 24hr schedule. I also get a consistent 8hrs registered on my CPAP so it doesn't seem to interfere with my sleep quality/duration either.
I buy melatonin that comes in 1mg pressed/powder pill form and just bite it to split it in half and toss the other half back in the bottle.
I've been doing this for 2 years now and have never had to change the dose. At one point I even considered seeing if .25mg would be sufficient but depending on the brand sometimes the pill crumbles up too much so I stick with .5mg. I've used Nature's Bounty and Webber Naturals and both brands seem to work the same for me.
I really wish I had figured this trick out a lot earlier in life as it would've saved me from missing out on a lot of opportunities in my career.
(more detail about my experimentation below)
Before I discovered this I tried everything from reducing screen time before bed, cranking up night mode in flux/redshift, abandoning coffee/caffeine entirely, working out earlier in the day instead of evenings, etc. _Nothing_ worked for me - my brain would remain wide awake and I would have to stay up until 5-7am before I even began to feel tired (where I would have to wake up between 10-11am for work).
I had even tried melatonin before too but it was a 3mg pill and it would produce very erratic results in my sleep quality. I'd sometimes wake up drenched in sweat or wake up feeling very groggy for hours so I figured melatonin just wasn't for me. It wasn't until I came across some advice on /r/n24 or /r/dspd to try .5-1mg of melatonin that I decided to try again (IIRC it was a post about how doses >=2mg can actually result in melatonin overdose and result in the types of symptoms I was observing - TBH I didn't really bother verifying that info and just figured I'd try .5mg and see what happened as I was desperate for a solution).
And for the record, with this approach I haven't had to make any other modifications to my daily routine. I continue to lift heavy in the evenings and drink 1-2 cups of drip/espresso every day.
The only situations I've noticed where this trick falls apart for me are:
1) if I ever try to push past that 20-40min period where I start to get drowsy, it results in me being awake again. This rarely ever happens and I usually just end up sleeping about an hour later. I make sure to take the melatonin just before I begin flossing+brushing and get in bed right after
2) for some reason drinking a can of coke/pepsi in the evening will keep me wired awake all night. I've had cups of coffee in the evening rarely which never had the same effect, but coke/pepsi will...
Anyway, just thought I'd share since this made a huge difference in my life - maybe worth trying/experimenting.
Low doses of melatonin can be really helpful, especially if people have tried all the "sleep hygiene" steps and that's not working and they don't need a z drug yet.
One of the problems of melatonin is that in some countries it's sold as a supplement not a medication, so the regulation is much less strict.
The dosing varies so much, even in product labelled as 1 mg.
> In this issue of the Journal of Clinical Sleep Medicine, Erland and Saxena systematically analyzed the actual melatonin content (and presence of contaminants) in 31 melatonin supplements purchased from groceries and pharmacies in one city in Canada (before countrywide OTC use of it in Canada was banned). Their findings herald what may also be true in OTC melatonin supplements marketed in the United States. Melatonin content varied from an egregious −83% to +478% of labeled melatonin and 70% had melatonin concentration ≤ 10% of what was claimed. Worse yet, the content of melatonin between lots of the same product varied by as much as 465%.3
> The most variable sample was a chewable tablet (and most likely to be used by children). It contained almost 9 mg of melatonin when it was supposed to contain 1.5 mg and also exhibited the greatest variability between lots (465% difference). The lowest melatonin content was −83% compared to its labeled value in a capsule that also contained lavender, chamomile, and lemon balm. Capsules showed the greatest variability between lots. Liquid supplements surprisingly showed generally high to median stability with low lot-to-lot stability. The least variable products were those that contained the simplest mix of ingredients, generally oral or sublingual tablets with melatonin added to a filler of silica or cellulose derivatives and were the most reproducible. The last disturbing finding was more than a quarter of melatonin products contained serotonin, some at potentially significant doses. Serotonin is a breakdown product of melatonin metabolism but could have medicinal effects and should be taken without oversight. In short, there was no guarantee of the strength or purity of OTC melatonin.
