Hi, Sorry not got your type of diabetes, however I have read about different types as I am very slim and active with a family history of lada, and my GPS had said my prediabetic state must be genetic.
But to answer your question a good bg reading in the morning would be under 6 to me.
Do you test your blood before and two hours after your first bite of eating any food to see what increases your bg too high. Whatever the cause of your diabetes it is important to avoid high bg levels for long periods of time.
