I have Diabetes 1 for more than 30 years. I am diagnosed with brittle diabetes, so my control is not always very good. But the last month have been strange. I use Novorapid insulin, which should be fast, but when I take it in the morning it does not react until around midday. Then I take the insulin for lunch and shortly after it rush down between 2,2 and 3,0. I have not changed the insulin dose, I eat the same as usual, I move the same as usual - everything as usual - just not my blood sugar. i also take Levemir morning and evening. Anybody who have experienced the same ?
