If you are that way inclined( towards carb control I mean) try "Dr. Bernstein's Diabetes Solution".
The doctor has been T1 diabetic since he was 12 and is still practising medicine in an exclusively diabetic practice in his mid 70s. and he'a complication free.
What he's found works for him, he has passed to his patients.
His way isn't for everyone, because it is quite restrictive. Still it's worth a read. I'm a T2 and don't use insulin, but I've found many of his principles very helpful.
If you can handle encyclopaedic volumes of information, look up Daid Mendosa's website, which is giganic too. you'll need to convert BG units, because it's American. The conversion factor is 18. To get our units, divide American numbers by it.
