I was able to have a continuous glucose monitor for a month in a half because a dear friend upgraded and gave me her old one with about 6 sensors left. The CGM checks your blood sugar levels every 5 minutes and creates a 24 hour graph showing you a general snap shot of what your blood is doing. My A1C was 9.4 after a month with the CGM my A1C went down to 8.8 I am on my way to my goal of 7. When Obama care passes It is my hope that I would then be eligible to receive a CGM.
