A different shape

Waking at four again. Not anxious, just awake, lying there listening to the boiler.

Slept through. Whole night, no waking. It has been so long that I lay there in the morning trying to work out what was different.

The sleep has changed shape rather than improved. Different, not better, and I cannot yet tell whether I mind.

Repeat study came back and the apnoea is much reduced. Ten years of that mask.

Kindly, to myself as well.
