Of mice and men
Instead, each and every time, I opened my eyes 14%, took a finger stick, entered it as a calibration--hoping to drag the sensor up just a few points so she'd stop alerting me. Alas, no such luck. On the bright side, my sugar was rock stable all night long.
Then at 8:17 a.m., after I'd been up and around about 45 minutes. Air Raid!!!
What? A high threshold alert? 193? No frickin way. My wake up BG was 127 and I haven't put a bight in my mouth yet today. Finger stick confirms the Guardian is out of her mind. Now how did that happen? I've got beaucoup calibration points in stable water all night long. The system uses the last four, weighted more heavily for the most recent. So how on earth do you run low all night and then out of the blue spike that high?
I'm guessing some sort of freak power spike. But to calibrate or not? If the sensor's out put stays high I'll wish I had. If it settles down I'll be biasing it high. It is a no win. I take the calibration.
Two hours post breakfast the children are neck-in-neck, so I guess I made the right call. Sensors often run on the low side on their first day. Medtronic admits that, and other users have told me that too. I've seen it some, but not as much as other folks. This sensor is the Hissy-fit replacement sensor, so it started its stint of duty in the early evening instead of the early morning. I'm hoping that, back on schedule, this won't be my average evening. I'll keep you posted.
