Another update
I continue to improve my sleep quality. I did go through a period when I was waking several times a night, wide awake, and thus having difficulty getting back to sleep.
I realised that the reason i was wide awake was due to adrenaline circulating . I had an overactive sympathetic nervous system at night. Why ? I thought perhaps it was menopausal anxiety, but I did not feel anxious. It then occurred to me that I was having sleep apnoea. I came across Dr Dylan Petkus on Youtube who describes how he 'cured' his sleep apnoea using yoga breathing exercises and a ketogenic diet.
I started to do 4-7-8 breathing whenever I woke at night. I just needed to do them for a few minutes and I would drift back to sleep. Better still, if I did them for 2-3 minutes before bedtime, I would not have any discernable awakenings and awoke feeling refreshed. My blood pressure readings lowered to normal readings.
You do not need to undertake any of his expensive 1:1 coaching, as all his advice is provided free on his Youtube channel. I did buy his book on kindle. This was only £4. The link to his most helpful video is here

It is worth committing to 2-3 minutes of breathing exercises before bedtime as a trial to see if it makes a difference. If it helps, please come back and let us know.
