A dexcom sale rep described CGMS to me as follows:

Imagine that you’re driving a car with a covered windshield.  Every few hours, the cover is lifted, allowing you a glimpse of where you are.  This is traditional blood sugar testing.

Now imagine that you are driving a car with a clear windshield.  You can see the bumps, curves in the road, and other obstacles as they approach, giving you more of an opportunity to avoid them.

It’s not perfect, CGMS, but I’m looking forward to a bigger view of my diabetes.  Even if it means moving one step closer to actually being a robot.

Tomorrow, I meet with my endo and dexcom trainer.  Stay tuned!
