I really don’t dose off my CGM… anything more than very small, insignificant boluses. This is an example of the things I’ve seen that contribute to my thinking… My CGM was showing a fast rising trend, and having had TWO bananas after my run tonight, it confirmed what I was afraid would happen— a big rebound. I almost “took care of it”, which would’ve meant a fairly aggressive bolus (a true rebound off of 2 bananas could mean I was headed for the 300s). Almost. I decided to double check just to make sure… and saw the 117. Decided against the couple of units.
This isn’t to say other people have this problem, and there are plenty of times my sensor is just fine, but these kinds of instances just make me leery to bolus without double checking first.
Oh! And I should include in here that it actually was a rising blood sugar. I watched it for a while after this just to try to get a handle on what was happening, and my blood sugar did continue to climb to about a 140, but my sensor at that point was showing a ~185 with two arrows up. I’m glad I didn’t do the insulin… I was dropping again within the next 45 minutes.
