For me, the back sleeping solved two issues. First, If I slept with my neck bent forward or to the side, I would have episodes of Central Sleep Apnea. I learned to use a pillow that does not lift my head. I curl it up so I have it next to my right cheek. This holds my head from rolling my head too far to the right.

Second, over time, my neck healed so I have more tolerance for other neck positions. I never finished NUCCA treatments. The NUCCA chiro had some billing issues that I could not deal with. But, the neck improvements have allowed me to experience far fewer Central Apnea episodes.

I still sleep on my back as much as possible. It is better for my shoulders.
