Have you tried sleeping elsewhere? On a couch? What about sleeping in a semi-seated position? Would that work?
How's your weight? Does it go up or down?
Finally, if you are in bed for 30 minutes and you haven't fallen asleep, it's probably way better to either get up and do some stuff or to just accept that you won't be sleeping and just stay there and go through your imagination.
But for most people, a CPAP machine is a great solution. There are few other serious medical conditions that can be more thoroughly addressed!
If you might have it, you really should look into it, there is a good chance your life can be turned around and improved more than you (pun intended) could dream of. Mine was!
Modern CPAP machines are quiet, comfortable, and only cover your nostrils. And they can save your life!
The test is apparently easy and you can do it at home with a device you get from your doctor and wear overnight, and his machine fits in the palm of one hand is basically silent. Anyone who thinks this is a possibility for them, I agree with you, get checked!
My partner is non-24 and generally manages a "normal" schedule. However, she sometimes has to roll her sleep, where she'll go to bed an average of 1.5 hours later each day, until she's back to going to bed around 10.
When she is holding her sleep schedule steady she uses light goggles in the morning (literally goggles with bright reflected lights on them) and low-dose melatonin at night (can't remember the exact dose). She also watches her meal times relative to when she wants to go to sleep. I think these things would be useful for someone without the non-24 issues, but are good sleep hygiene things.

Also, D3 and Magnesium work very well together. In fact, if you add more D3, it's going to use-up even more magnesium.
There is a negative correlation between RDA fruit consumption and diabetes.
Of course if you're drinking 2L of juice a day you're gonna have a problem, as you would going ham on any kind of food. (ANY)
If you eat the right meats, like liver, you get more vitamins and minerals then you would from fruit. So if you know what you are eating, it's fine to cut off fruit.
Note the operative modifier 'too much'
You can eat your recommended daily intake of fruit in one sitting with no other food and still remain below high GL levels.
Digestion is a complex process. Your model that anything containing fructose is bad is not supported by any data / analysis I am aware of, and contradicted by nearly all of it.
Mammals process most of thier fructose consumption in their small intestines. Only high doses that overload this capacity lead to harmful spillover to the liver etc.

Fruit consumption is inversely correlated with all-cause mortality as best we can tell. Probably something to be said about people who eat fruits being among the more health minded individuals as well and skewing results but it’s probably not “unhealthy” to eat fruits.

People consuming fruit could be more healthy individuals in general, exercising and avoiding other types of food which might have more effect than consuming fruit. So be careful about drawing conclusions from correlations or epidemiological studies as you have to consider other possibilities.
I'm in my 30s and eat what many consider a very healthful diet - virtually no sugar, just veggies, high quality fats and proteins, and minimal fruit. I spend 7-9 hours in bed; yet wake up feeling exhausted every. single. day. I'd love to exercise, but I'm too continuously tired to get started.
Melatonin, when taken via dissolving sublingual tablet (1-3 mg), makes me feel a bit sleepier, but doesn't often keep me asleep through the night. When swallowed via a capsule, it makes me feel like I've been hit by a bus for the entirety of the next day, even if I slept the night before.
My own research led me to magnesium glycinate, which helped to some degree (maybe I wasn't taking enough?), but didn't solve the problem. My biggest trouble is falling asleep - I can be dead tired, but as soon as I'm in bed, my mind goes nuts, and I lie awake for hours. Then, by the time my body is in nice deep sleep, it's time to get up, and the deep sleep is disrupted.
I recently had an appointment with my physician (who practices integrative medicine and is not your typical MD), and he told me to try a relatively new formulation of magnesium called Magnesium L-Threonate, commercially known as Magtein.
It is apparently the best type of magnesium for crossing the blood-brain barrier, and thus, likely the best at addressing sleep issues.
I've been on it for about a week now (taking 1000mg 2 hours before bed and 1000mg upon waking in the morning), and have slept better in the last two nights than I have for a long time. Here's to hoping it keeps working!
I also use a couple other hacks to help me sleep - at night, about an hour after the sun sets, I wear "blue blocking" glasses (the UVEX S0360X fit nicely over my prescription glasses). Sounds (and looks) goofy, but for me it creates a noticeably stronger "sleep pressure" than I'd experience without them. I also wear a mask over my eyes when sleeping, to block out any ambient light, and I just started making an effort to listen to music while waiting to fall asleep. I think all of these things help to some degree.
