I saw the doctor this morning. I do have 'moderate' sleep apnoea. As I suspected, the restlessness in the second part of the night indicated that I was frequently stopping breathing and almost waking up as a result. I don't snore much.
However, none of my other health markers are a worry. My blood pressure is low, and although my cholesterol and blood sugar levels are above normal they are all lower than they were last year. The only thing that needs to change is my weight.
My weight has gone up a bit, and has stayed up, because of the trouble with my knees, which made it difficult to exercise. However, now that my knees are feeling much stronger and less painful I can walk, and get back in the pool. The doctor suggested 12,000 steps a day (eep!). This week I've generally done 5000, and one day I did 7000. So I need to try and build more into my routine.
In short, I don't need to use a CPAP machine, or a jaw-breaking oral insert. I need to lose weight.
And that will be the last health-related post from me for a long while, god willin' and the cricks doan' rise.
