Thank you for your comments to my first post. I should have told you that I am a Type 2 diabetic. In fairness to anyone who reads my notes I should also make it clear that I am not a physician and have had no formal clinical training. I worked in engineering until I retired at 65 but during that time, and since, I have learned quite a lot about the human body and how it works, plus nutrition, which has been a big help to me and I hope will be useful to others. I'll begin with the situation as I see it in my next post. I hope to get lots of feedback.
