My G4 usually takes at least 24 hours to acclimate a new sensor and begin producing reasonably accurate readings. That said, I've become very frustrated with it on the first night after putting in a new sensor. Last night it kept alarming me every half hour telling me I was low when I really wasn't, "No I am NOT 57, I am 91!" "No, I am not 69 I am 93!" I finally got tired of getting no sleep and I just turned it off (that's one advantage over the 7+, you can turn the G4 receiver off).
Does anyone else have those kinds of issues with their G4? Night time is my best bg time, for the most part I tend to flatline in the 90s all night as evidenced by the G4 sensor when it's good and broken in. My night time bgs are usually very stable, I've worked hard on getting those basals correct for me, although there can be occasional(not often)times when it does fluctuate, due to unusual circumstances.
Now I'm to the point, I think I'm just going to turn it off that first night and not use it at all, but that kind of defeats the purpose of me getting it. Has anyone else experienced this type of inaccuracy and found a solution? I don't mind it so much during the daytime hours, but at night, it's just getting unacceptable. I really can't function the next day after getting little to no sleep.
