So I've now been using the Dexcom for three weeks (my first sensor lasted 16 days, and I'm doing a second just to make sure it wasn't a fluke). One of the things I've been wondering is how those of you who use CGMs use the data. For example, if it says I'm low then I test and treat. But if it says I'm high, I've learned that often if I wait it'll start going down on its own and if I correct I end up going low. Or, if I'm going down, it doesn't necessarily mean I have to eat, because I might level off or start going up again.
I have managed to "head off" about two lows so far. But at other times I eat and end up going high. And I haven't managed to deal with highs any differently than I would when testing.
I know part of this is probably that my pump settings are off. I'm still trying to sort out my overnight basal rates! My overnight blood sugars are better than they were, but I'm still dropping or rising by about 3 mmol/L during the night. The daytime is even more chaotic. I haven't even tried working on those settings yet becasue I'm still trying to figure out why there are some days where I have lows and no highs and other days where I run high all day and other days where there's a mixture of both!
I do know for sure that when this sensor is done I will be buying the Dexcom G4 system.
