just going to leave this link here for a video I watched in case someone in the future stumbles upon this thread and it helps them. more about psychological aspects of CGM. it’s at a third grade comprehension level - perfect for me 
more of what you all (and the Inside Exercise link Dr. Andy posted) have been saying about being careful with these things.
I am happy I got it because it will be the impetus for learning more about nutrition and myself - and ultimately changes in habits / behavior. but I wish I read this thread and came into it with a different mindset.
