Blood sugar / glucose monitor?

I'm type 1 diabetic and take insulin. I recently switched from the Libre to the Dexcom and I can say the Dexcom is more reliable and, accurate than the Libre. I constantly had issues with the Libre but have had very little issues with the Dexcom. I also switched because the Libre 2 is what I had and, they don't have a phone app for the Libre 2 but, the Dexcom does and, its just one less thing in my pocket if I can just use my phone for the CGM. Your not going to get a CGM unless your diagnosed with type 1 Diabetes. Since you are border line you would have to pay out of pocket for a CGM. I also use the Walmart (Reli-on) meter and its cheap and works well. My advice is to do what you can to avoid taking insulin as it's a pain in the ***. Excercise..eat better and, you can stay off or, prolong the need for insulin as long as possible. My best to you and any other person dealing with blood sugar issues.
