I decided to go without Dexcom for a few days. The current sensor stopped working -- and man it was a good sensor. Lasted 10 days, and was accurate the whole time.
However, if I put in a new sensor today, I'll have a sensor failure during a dog show next weekend, and it's not something I want to deal with. I'm going to try going without until Monday.
I think it is probably a good idea to give my skin a bit of a rest anyway. The Dexcom is hard on it.
This is the first I've been without CGMS I started in July.
