Terry - The apparent low between 5-6am is intentionally induced.
I have a significant issue with dawn effect 20-30 minutes after rising (generally I get up 5am).
I’ve now taken to tripling my basal (pump) dosage from 0.400U to 1.300U at 3:00am, as well when I awake around 3AM I also pre-bolus an additional 2.0Units.
If I don’t do this my sugars spike to 10+ (over 180) and take 6-9 hours to return to the norm.
Aside from that minor wrinkle life is good
