While I was in Walmart several years ago, I came upon a man in the pet section who had a dog. On that dog’s harness was clearly embroidered the words, “Diabetic Alert Animal.”
Yes, the cat saved your wife’s life, without a doubt.
If anyone is interested, I would recommend the book and website by Dr. Richard K. Bernstein, M.D.
He is a type I diabetic of long standing. He was able to reverse some of the diabetic sequeleae in hi own bdy through long-term strict control of blood sugars.
He is an advocate of counting carbohydrate grams and dealing with “small numbers” in controlling diabetes.
He pioneered the use of blood glucometers in keeping blood sugar within a narrow range. He himself has normal blood sugars.
H believes in timing meals, and eating prettty much the same amount of different components (proteins versus carbohydrates) to keep blood sugars on more of an even keel. He himself takes very small doses of insulin.
His book is available on Amazon.com. He also has a website with forums, where you can ask questions.
