I was primarily struck by the awesomeness of this whole autonomous glucose regulation thing. My last meal is usually around 18:30 in the evening and during the night glucose would fluctuate around 4.5 mmol/l between 4.0 and 5.0 in 1 hour periods, like a crappy PID controller that needs a firmware update. Other nights it would be flat instead of fluctuating, but unfortunately two weeks were too short for a controlled experiment, meal repeats and figuring out what caused the difference. Some nights it would show a couple of hypo's where glucose would drop to 3.5, quickly to be countered by an increase. I didn't notice a thing.

Additionally every morning before my alarm went off, I could see my glucose increasing, most likely preparing for wakeup, all by itself. Amazing!

It gave me a new-found respect for these otherwise invisible processes happening in this fleshy vessel on autopilot with closed cockpit doors. I only got to peek through a small window during 2 weeks.

Now imagine having that entire responsibility yourself, having to do it all manually. That's what we type 1 diabetics do every day!

The nighttime fluctuations could be legit changes in glucose level, but could also be weird sensor issues. The sensor will often give low readings when lying on it in your sleep. These are referred to as 'compression lows'.

The morning glucose spike you noticed is called the 'dawn phenomenon'. I inject a little insulin every morning to counteract it.
