This is super interesting. I did a sleep test a while back and they were on the fence with recommending a CPAP machine. My experience isn't like what is described by most people with sleep apnoea. I don't wake up tired or groggy. I do snore from time to time.

The doctor suggested, cutting out alcohol, and sleeping on my side rather than back. I've paired that with a smart watch to keep a track of my O2 stats and feel fine. I'm hoping to avoid all machines as long as possible.
