For me it was “buy high quality pillow” because you sleep for one thrid of a day etc. I needed a new pillow anyway so I came to the store and bought the best they had. And it was … ok. Like it’s a fine pillow but my sleeping haven’t improved really, it’s basically the same. So I was disapointed :(
So, which life pro tip disappointed you?
Nah. I’m mostly a side sleeper but even on my back, my head normally compresses the pillows enough that it’s comfortable. I occasionally wake up having tossed a pillow off to the side, but that’s rare.
