Query: Life Saver!

I was diagnosed as a diabetic with no prior family history and a BS reading of 536. The future looked bleak until I purchased this book. 3 or 4 months later my FBS blood sugar was down to to 83-105 average. A1C 5.5. It came down that much even without excercise. The book gave me a sense of pride in taking care of my body. Instead of being happy for, me my doctor was indifferent and acted wierd after he discovered that I had stopped giving myself those painful Lantus injections and taking Glyburide long ago. He reluctantly discontinued all BS medications asking how I had done it. This book is very powerful, written by an engineering genius. He also addresses many other health issues attached to the disease. If you want to get your BS under control with a possible cure, this is the book to get, period.
