The hose became easier for me to deal with after I used a bungee cord together with a wall hook to keep it mounted above the bed.

I use a hook too, plus a mask with the hose connection at the top of the head. Looks ridiculous, but it's better than the usual "oxygen mask" hose setup, even with a nasal mask. Both things help, but I'll never get completely used to the hose's annoyance.

Also, I recommend a hose cover like <https://www.amazon.com/dp/B0BLBTF38Y> so it slides more easily on the hook.

Yeah same. If a tubeless variant were to somehow be invented (portals?), I'd be a happy chappy
