With the help of this little book, I was able to reduce my blood glucose from an average 9.5 mmol/l to an average 6.2 mmol/l. Further, the peaks and troughs of my blood glucose have been smoothed out, and it's those peaks which do the damage with diabetes complications. The information in this book is concise, easily understood and there's lots of it. If there were 10 stars, I'd give it 10 but I have to settle for 5. My advice to anyone with diabetes or looking after someone with diabetes is buy it!
