Ah, yea. Varying sleeping locations, I've done that a lot, unintentionally. I've slept in humble homes to mansions to far out locations (my own place being a humble home). My best sleeping moments are when I go camping and rise and fall with the sun. That's the only time when I am capable of sleeping normal, waking up and falling asleep with the sun, no clock needed.

Here are my experiences to what you said.

It's darker: I use a sleeping mask.

It's less noisy: I used earplugs but I have tinnitus and it acts up when I do that. Currently though, it's not noisy because of Covid. Maybe I should have a noise cancelling / ambient white noise system. The normal tinnitus levels don't bother me, airplanes flying do.

Better bed: turns out, I love a mattress on the ground the most.

Sleeping next to people: that's funny, I sleep better sleeping next to someone! Well, we all differ.

Regarding safety: that's how I feel when I sleep next to someone. Not that I feel unsafe sleeping alone, not at all. I simply feel safer.

Happens to me and it's none of all that. When at you parents it feels like a kid, no stress, the world is a happy place. It's just psychological.

You're so off the mark with your comment, the only way my message might get through to you is by being very direct.

You're right, there are also a lot of people who are capable of simply going to sleep. But if you think that there isn't a sizeable group of people in society who have difficulty with this, then I have news for you.

You're wrong.

Also when I state I have issues with this for 25+ years, do you really think I haven't heard these type of comments or advice? Because if you think your comment is something that I have never heard before, or am not aware of, then I have news for you again.

You're wrong.

The reason I'm replying: you're either trolling (if so, touche) or you're serious. Since you have 500+ karma (aka leave some good comments), I simply wanted to give you this feedback. Because I know my stuff when it comes to sleep by (1) dealing with, by (2) studying the neurobiology of it in my psychology undergrad multiple times. Moreover, I know the group of people I fall in (the group that has trouble with sleep). I can't speak for them but I have an idea of how they feel and think since I'm recognizing what they say in my own experiences.

===== Melatonin ======

The effects of melatonin are super noticeable. It's like taking drugs: you pop a pill, and feel different 30 minutes later. Melatonin makes me feel drowsy.

There is no placebo here. After 15 to 20 minutes, I always get irritated and ask myself: why doesn't it work?!

It does, just a bit later.

===== Vitamin D ======

Sorry that I'm sourceless on this. I read somewhere that melatonin and vitamin D are inversely related in their cycles of when they peak. Someone suggested to take it in the morning.

Regardless of whether the timing is off or right, vitamin D is needed to not be depressed [1]. So this part might be a placebo (like I care, I'm pragmatic) and at best it does something.

I do notice that it indeed prevents me from feeling like shit by virtue of sitting inside all the time. That also might be a placebo (I still don't care, placebo's are demonized and it's a competitive advantage if you accept it). The trend has been going on for 2 weeks now.
