I am having a serious love/hate relationship with our new Dexcom that we have been using for 3 weeks now. We get good numbers sometimes. Sometimes we get good arrows telling us when he is rising or crashing. But the rest of the time I am getting woken up at 2 am with beeps for crazy "imaginary" low blood sugars or beeps in the daytime for lows/highs that aren't there. Sometimes I get ???, no arrow at all or LOW despite normal sugars. I try to recalibrate, I try to change the sensor, I try to call tech support (very sweet people BTW), but at the end of it all I just want to throw the stupid thing in the toilet and get a new one. So far this Dexcom, AKA Dexter by Parker, is just driving me crazy and prompting me to poke his sweet little finger way more ofter to than I should have to in order to get Dexter recalibrated. Super frustrating!
