That ain't cheating. That's doing what you need to in order to control your diabetes as best as you can. I also found the Dex to be more accurate than the Medtronic CGM, so I switched. The Med was missing severe lows, and I don't feel them until they are in the 40's, and since I live alone, that's too dangerous. The Dex has picked up every one, even if the number is not the same -- it's the alert that tells me to check my BG that I need. So more power to you, and good luck!
