Do you carb count at all, adjusting quick insulin dose according to the amount of carbs?
A good suggestion, is to put some real input into data collection... boring and can be time consuming, not no real other method..
Keep a dairy..
The more information you put in it the better the picture, so BG, insulin dose, amount and type of carbs, exercise you've done etc..
Then you will get a better idea what effects your control and where and what you may need to adjust to improve..
And to ensure that your basal/background is correct you really need to do some fasting tests..
Two books I reccomend Think Like A Pancreas and Using Insulin, I have the latter, but both are very good books, easy to use and understand. (and nope you don't have to read it cover to cover, just pick the chapter/section you need to refer to)
Insulin pumps can be used by any insulin using diabetic, it's only the NHS and the NICE guidelines that depict who may or may not be funded..
I've got an insulin pump, as I am very senitive to insulin, so use very small amounts, and their is noway that you can get a 0.1 unit from a pen/syringe combined with a pronouced DP, So control wasn't easy, as very easy to overshoot, and I was injecting 6-10 times a day...
