I started using the Dexcom 7+ last November. It has really helped me with the lows. I drive 90 miles a day for work on big highways and was getting very anxious because I would always wonder where my blood sugar was. Now, I can see the trends and feel good about driving. That is my number one pro to the CGM. Even if the number is not perfectly accurate (which it actually is pretty good the majority of the time), the arrows (raising fast, raising steadily, steady, lowering slowly, falling fast) help me the most. Even if there was no number that came out and it was just the arrows, it would be helpful. I still check with my monitor pretty often, but I like my cgm for running and snowboarding…now when I am working out I dont need to bring my monitor, i just bring glucose and my cgm.
As for comfort–it doesn’t bother me at all.
-The 12 hours with my cgm after changing a sensor is almost worthless. I get a lot of “???” readings the first 12 hours…but I have learned to just change it before bed and stay a little higher for that first night.
-I have to carry it everywhere, so its another thing to have…but I got used to it
-Now that i have it, i cant imagine not having it! (dont know if thats a pro or con!)
