I just bought the book on amazon and was a touch disappointed. The book seems to be mostly about chaos theory and how it can be used to describe the control of diabetes. I have only read the first chapter so far, but a flick through the chapters did not uncover an tips on how to control the "rollercoaster". I will add a further comment when I have read the whole book. If you are looking for a book to tell you how to adjust insulin dosage, cope with sports, allow for residual insulin, then this is not it. If you are looking for help coming to terms with the fact that you'll never get it all quite right, then this is what the books seems to major on.
I will read it, having spent the money!
