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?
Ok… I'm in the same boat, severe sleep apnea because of it. I sleep with 2 pillows, a dense down filled for the base and then a soft pillow on top for comfort. Keeps my head at the right height but also allows me to roll over.
Never thought about building a pillow
