I am starting to truly understand the need for a CGM. I used to just think it was going to be another way to innondate myself with data that will go by the wayside. But the more I read about it and the more I interact with people who used it I am starting to see the value of knowing when your sugar is either dropping rapidly or balancing out.
This would be especially useful at night. I have been battling my evening sugars since forever. They are severely unpredictable and any alterations to my basal rates make a major swing. So my basals stay as they are for now and I adjust accordingly to my bgs and hope they work.
My sensitivity over night is incredibly high. I have a basal of around 2.0u per hour which is low for me, as it jumps to almost 4u at 6:30am (when I also take a metformin tablet for resistance in the mornings).
Overnight I can spike to 18.0-20.0 one night, and correct and come down to around 10.
The next night I can wake up at 1am with a bg of 2.2 on the exact same basal rates and the same schedule the day before.
I think the key is my before bed sugars. I can kind of grasp them, but if I knew if I was trending down or balancing out, I would be in a much better place to correct accordingly.
