On March 17th, I relied on a combination of insulin and exercise. My lunch had been light on carbs, so I bolused only 4 units. Then I nibbled a bit more as I prepared dinner and then ate it. It seemed all was fine according to my CGM, but I’d eaten a fair amount and my eyes were feeling twitchy in the way they do when my BG levels are too high. I decided to calibrate and confirm that the CGM was correct. In fact, it reported my levels about 40 points too low. I was actually above my “high glucose” threshold. That prompted me to do elliptical for 35 minutes to bring it back down to around 70 or so. I figured it would rise again as I slept, but I was happy to see that my levels remained level, and even dropped overnight.
