Sorry, I don't remember if they measured her c-peptide levels or not? Too many replies to sift through.
I still have a c-peptide of 1.1. So, once the b-cells I have left get over glucose toxicity, they'll start pushing out a little insulin here and there which will further confound things..
Also... I may be on a low level right now, but it's not entirely controlling it... especially when they tried to set me up with a I:C ratio of 1:20. My body laughed at that and it sent my glucose skyrocketing. The 'Using Insulin' book came in the mail the next day, and I love it. It is helping so much. I like it much better than Think Like A Pancreas, though that book has been a good read as well. It's just somewhat basic.
I used the website LaGuitariste sent and I suppose based on weight 35 units is where they might typically start someone my size out at. But as already said, everyone is different.
Exercise is very important for everyone, especially if you have diabetes.. it can help control your BG a little better. I like to play 'Dance Central' for the xbox kinect (yes, i will admit it!) and it helps bring down my glucose. If I could kick myself into a regular routine, there's a good chance that'll cut down on the amount of insulin you need too..
Also, depending on how much you want to read about the disease... there is an endocrinology textbook on Type 1 Diabetes that I just got and is wonderful because it explains some of the major theories and incorporates current literature as well as talking about treatments and such..
The ADA also has a book on clinical management of type 1 diabetes, and though I have gotten it, I have not read through much of it yet.
Having information makes me feel better, for some reason.
