For the last 11 days I haven't taken any basel or rapid acting insulin. For the first week I ate what I wanted - carb overload - and for the last few days I've eaten very little and practically no carbs. I only tested about 3 times during the first week and got readings of 10.2, 11.6 and 4.6. The last few days I've tested every few hours and I've gently moved between 4.9 and 6.0. What's going on? Why are my levels not sky high? Am I not really diabetic (and there was some confusion as to which type I was at diagnosis)? I'm worried about whether it's bad news not to have any basel insulin in you as, apparently, is used for other functions in the body aside from dealing with carbohydrate.
