I can buy a LIBRE sensor for $38 for 14 days. I am not on insulin and I don’t ever want to be either . Insurance won’t cover it for me since I’m not an insulin user, but it does give me valuable information so it’s worth the cost . So I use the monitor to see what foods set off bad reactions. I definitely see how changes in your diet can improve your overall diabetic health and this is one tool to help you get there.
