How has the use of CGMs informed or improved your management of patients with pre diabetes or diabetes not on insulin?  

Yes. It has led to behavior modification with diet and movement choices.

Sounds like a great idea in theory, although sadly, I am afraid there should be a minimum threshold in the level of health literacy, self-awareness, and food security, for true engagement. Which would in turn create an inequity issue. Maybe criteria should be created, or even a scoring system, to us...
