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?
I have sleep apnea and I have found a bumper belt works wonders. It’s a belt you attach to your back with several air bladders that keep you on your side, even if your body is included towards back sleeping. It travels very nicely. Just deflate the bladders and roll up the belt.
