This is a great book. Unfortunately, it is written in American and you have to interpret some of the words. However, it is a very good guide for anyone wanting to get a grip on their diabetic control. Although all types of diabetes and all control regimes are covered, the book is most useful for those on muliple insulin injections (basal bolus regime) or those using an insulin pump. Much of the thinking in the book is now being taken up by forward-thinking clinics, but (perhaps) not most GPs. It is interesting to read the original script for some of the advice I've been hearing! Do buy it. It is very helpful and practical, with just the right amount of science to support the advice. It may well make you question the way you've been doing things! And for me, it worked.
