  1. A few years ago my doctor said I was pre-diabetic based on Hg A1C scores. So I started testing my BG with the finger pricks. My BG was rarely high and fasting BG improved greatly by dropping refined carbs from my diet and increasing the intake of vegetables. A few weeks ago my doctor said the CGM were now very affordable and he prescribed the Freestyle Libre (14 day sensor) to me. My copay was only $10.85 per sensor and I didn’t bother to get the reader since you can get the APP on your phone and get readings that way. I know the Dexcom is Dr. Attia’s preferred CGM but I have had good results with the Freestyle Libre. I’m not trying to be an advertisement for one or the other. Anyway, after wearing the sensor for three weeks now I agree with Dr. Attia that being able to see what one’s BG is at any given time is fascinating and helps control my behavior. My guess is that, like Dr. Attia, my red blood cells live longer than the average and that causes my Hg A1C to be higher (a couple months ago 5.7).
