I would recommend you find a copy of "Dr. Bernstein's Diabetes solution" It's by far the best book I know on the subject. It is American and so the units will be unfamiliar, but conversions are straighforward.
there are several web sites that are useful in addition to this one. D-solve and David Mendosa, are 2 I use often.
I prefer a low medicaion low carb method of control myself and still use no more medicine than I did 10 years ago. In fact less. I know I could manage on none at all, if I were 100% on diet, but I do have a few treats every now and then.
The more you learn and understand the better you will do. This condition depends much more on the patient than the medics
good Luck
