Not OP, but I went with PopOS. I’d used it in a VM for a few years, so I decided to install it when I finally decided to make the switch after Microsoft decided to reveal that dystopian “record everything on your screen, coming to a PC near you soon” bullshit.
Magnesium threonate cured my insomnia, it’s fucking wild how well it works. I’d tried everything until I discovered it, from melatonin, to antihistamine sleeping pills, all the way to downing 350ml of whiskey every night just to force sleep.
Magnesium works better than every single thing I’ve tried (but you HAVE to let yourself fall asleep when you feel it starting to work.)
