I don’t remember hearing the Dexcom alarm last night or taking any insulin but I must have. When I looked at my graph for overnight, I went high and came right back down. According to the Dex reports, I peaked at 203 at 2:18. I don’t know why I went up or why I came back down, but I guess this is the diabetic version of sleep walking.

Or you were having an exotic dream . Glad to see you’re still using the CGMS despite not having the pump anymore.
I will never tell!
I have always said if I had to choose between the 2, I would rather keep the Dexcom.
