CGM newbie here is now on 3rd sensor. G6.
Definitely see what everyone’s talking about, with the first half day or so on a new sensor. The sensor reading goes all over the place with no rhyme or reason and several times the screen just refused to give me any number at all and calibration attempts just whacked the system out. The wackiest results shown below. In the first hour after the two-hour warmup, the system repeatedly alarmed about impending sever hypo continually although all my finger sticks showed me stable at 140, then when I tried to calibrate the the thing it just went offline. Then overnight crazy stuff happened too.
So, there’s little to no value to me in sensor readings for the first half day, and me trying to calibrate the sensor can’t be good because those readings have nothing to do with where the sensor will eventually settle out and will just confuse the Dexcom brains. Right? Lecture me if I’m wrong and I will learn!
BTW, about 12 hours in, everything did settle in
