A different shape

Recording this for the record.

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.

Long run Sunday.
