I second that about Apidra, has helped us so much with my newly diagnosed 11 year old.
Pavlos when I was DKA 6 years ago and in a coma in hospital, my BG was 1300. The doctors had never seen a number that high. I was in a coma for 5 days. So yes it is possible. I'm lucky to be alive.
When I was diagnosed my BG was over 1000, how much over that I don't know. and I wasn't even in a coma. Still walking, Still talking, still able to worry about schoolwork. 1200 sounds absolutely normal for diagnosis to me. As for lows, I've been in the 20's and still able to function without assistance.
