Almost never! If it has been steady and accurate and I am somewhere without my meter then I might use it.

Same here. Sometimes if it's a tiny snack I'll just go with the dex, but rarely.

very rarely. It's not always the best bet to go with your dex readings. I have been up to 100 points off, even with frequent BG entries. Be careful.

I may give DD a snack based on the Dex saying that she is headed for a low, but I don't dose insulin based on it.

Yes ... But not too frequently.

In terms of food, if the dex is in an acceptable range I roll with it...but for correcting I only do it if I'm without my meter and even then I'm super cautious with it and tend to lowball the corrective dose. I used the number as gospel once and went low in an inconvenient place, so now I know better to test first as even a small variance can change my dose.

When is low I will go ahead and suspend my pump and have a snack - if I have 50 or 30 I will still have a snack, so it will not add too much value

I'm still fairly new to the Dexcom, but I did have one day where I dosed off it when I was out with friends, for convenience sake. Coincidentally, that was the day the sensor started going crazy. That was not fun.

At this point, I wouldn't do it without a recent fingerstick to back it up.

Yes, always. Calibrate it right and it's accurate enough to bolus off of every time. I've never had an issue with that in 3 years of using Dexcom.

How do you "calibrate it right"? We always get some wonky numbers - especially on a brand new sensor

Once a day, when your sugar is dead level. I read it here all the time of people calibrating with every finger stick, even if it's not level, and that always throws it off.

Andy, I'm curious what you mean by "when your sugar is dead level". And when it alarms you to calibrate 2x a day, do you just ignore the alarm for the 2nd calibration, or do you disable the alarm?
