Thanks Batts and Katie! :) Today is a great day in the Land of Kim.
The insertion part of wearing the sensor does hurt a bit. But, once you've worn the sensor for a few hours, it sort of just becomes a part of you. Most of the time, I don't feel it, unless I bump against something, etc.
My favorite spot to use is my lower back. It's less "in the way" there, and doesn't seem to get unstuck as quickly. I can usually go 4-5 days before I have to call upon my IV tape for reinforcements. I also wear most sensors for 2 weeks, instead of the FDA-approved 1 week.
There really aren't any *major* bad parts about it, for me. I'm already used to wearing the pump, so the CGM is just one more robot part to add to the list. The Dexcom lays pretty flat to the skin, compared to the MM one I tried out - so it's less noticeable under clothing. Sometimes, depending on where I place the sensor, you don't ever see it at all. There are times that it won't take readings (like when I'm leaning against it), which is annoying, but it bounces right back after a few minutes. The only main issue I've had was the receiver dying on me a couple of weeks ago. But, as a testament to their great customer service, Dexcom overnighted me a new one, no charge, and I was back up and running.
