I'm considering trying to get my insurance (Wausau/Fiserv) to cover the cgms. My biggest problem is that I HATE lows and try to avoid them and end up running high. I'm wondering if the cgms "catches" lows right away. It seem that if the fluid that it's measuring is 15 to 20 min behind the actual blood sugar, it wouldn't really help prevent lows, because by the time it gives a low reading you've been low for a while and/or are much lower than what it says. The literature I've read about it seems to give mixed answers about this issue. Does anyone have experience with the cgms and know about this? Thanks!
