I have been frustrated but never completely stopped…i do know some who have though…it think it really depends on what you need it for. My BS tend to rise really quickly after eating…and although i am getting better, i am not great at carb counting…(or knowing how many i will actually eat b4 i eat)…I can tell when i see how quickly i am rising that i need to correct…this helps me from going super high and staying there. CGM is the #1 factor in getting my A1c to 6.0 and 6.1%—prior i was always in the low 7’s.
I use mine almost constantly, but have jsut recently gotten comfortable taking a day off or 2—it has helped me adjust my basals so i dont fall low so much during the night—hypo unawareness was the main reason for my purchase.
Mine is accurate(within 20%)…90% of the time…and trending is right on 99% of the time. day 1 and 2 are sometimes not very accurate, but trending is still right on.
Also, in a previous post i read about meter accuracy—with Dexcom you see it first hand…just this mornign i restarted my sensor…to calibrate Dex requires 2 finger sticks…my first was 195 and second was 165—that is a pretty big difference—so i try not to be too hard on my Dex when he is off.
