Well, I checked with Dexcom and I did put the sensor in on Saturday morning, so they do feel I got good life out of it. I am, however, glad to be rid of that box. I am not sure, but I think every one but that one ended early.
I am definately going to wait until the morning to insert, but might put it off a few days, just because I'm doing an agility trial and I'm not sure I need the extra hassle. I also think my skin needs a break. I'm still convinced it is a bit of a skin issue.
