My son was diagnosed about 3 months ago...so I am NOT AN EXPERT. But, I also wonder why you need to keep your BG under 100? My son't target is 80 - 180. We don't even correct for readings until they are above 150. At our most recent visit, most of his readings were in the 110- 130 range and they were very pleased. IN fact, when we went through a spell of low sugars (and never as low as 37) they decreased his insulin because he was always below 100 in the am and they didn't want him starting the day that low.
You mention that you can't afford an endocrinologist. If your insurance does not cover one, can you see a diabetic educator? Where are you located? What is your local hospital? Do they have a program for people who can't afford to pay? Have you contacted JDRF? I wonder if they know of resources that can help you? 5 months is not a long time. It seems like you need someone to give you guidance. Even if you can't afford the doctor, it seems like there should be some other trained professional that can offer resources with your logs etc that maybe won't be as much.
I feel for you and I"m very concerned for you. You're one of the ones that needs some kind of heathcare reform the most. We need lots of help to understand and get this under control.
I pray that you can get the help you need. If you can't find anyone to help you.... and you live in a town with a university or something, I would go so far as to call tehir endocrinology clinic and tell them your story and ask what resources they know of that could help you. Good luck!
