Just thought I would provide an update, and thank everyone for the advice because the last two weeks have been awesome.
I had the bad luck of running into a bad patch of sensors. That was a total buzzkill, but Dexcom’s customer service quickly got replacements to me.
I thought that every BG reading should be entered for calibration purposes (makes sense, right?), but as many people pointed out, that’s dead wrong. I’m entering maybe four readings per day while I’m at a steady state, and the Dexcom has been eerily accurate at telling me my blood sugar. Dexcom’s user manual is not so good on this point.
This device is indispensible in catching highs. With the info I’ve received from the Dexcom, I have become religious about bolusing well before meals, and I have reprogrammed my nighttime basal rates to better compensate for dawn effect. This would be all but impossible with a standard glucometer.
Despite a very rocky start with bad sensors and a user manual that could use some revision, they’re going to have to pry this thing from me. Thanks again to everyone for their help.
