Yes, but who prick their finger every moment of the day to check their blood sugar? It's more convenient to do it in the morning.I would be more concerned about higher peaks of blood sugar than a simple elevation when I wake up.
People are too concerned with fasted blood sugars when it doesn't paint the whole picture
Waking up with a blood sugar of 110/115/120 is very different from waking up with a blood sugar of 65/75, maximum 90.
