I arrived at this number from trial and error. If I add insulin at a lower number, my risk of hypoglycemia goes up. But if I don’t add some insulin at this level then I risk a higher glucose level and the burden of adding correction doses later. I find as my glucose level rises, it’ll take more insulin total to correct it than it would if I took the correction around 6.7 mmol/L.
There are few hard and fast rules with diabetes treatment. Many diabetes medical professionals are so fearful of hypos, it clouds their judgment and common sense. Instead, I would counsel doing your own experiment, taking note, adjusting and trying again. I would carry some quick acting glucose and watch my CGM for safety’s sake.
No worry, however. If you’re not inclined to exercising in the early morning, there are other tactics. I actually exercise in the afternoon and my first interest in the morning is my coffee! I just thought that this might deaden your FOTF glucose rise.
You could experiment with your 9 pm snack with eating a hard-boiled egg. As I’m sure you know, the protein acts much more slowly on the metabolism and doesn’t require as much insulin.
I encourage you to consider the idea of experimentation as a valuable tool. When I experiment, I don’t think of it as permanent change of habit, just as a way to see how my body responds to that change.
I realize that we as humans love our routines and resist changing them if we can avoid it. I found, however, that I made the biggest gains in glucose control when I put every cherished habit up for examination and dispassionate analysis. Turns out, for example, that bagels are not essential to my well-being and happiness!
I’m sorry to read that your drug plan does not cover Afrezza. I recently lost my insurance coverage of Afrezza and I will start buying it “out of pocket” as soon as my buffer stock runs out. It’s a valuable tool that I don’t want to give up. I realize that this option is not economically open to everyone but there are discount plans that uninsured people can use.
