Seem to be eating through sensors
Last one lasted just over 3 days. Replaced on Thursday.
This morning I woke up and my BG was 9.9. I calibrated and bolused. About an hour later suddenly I'm 2.2 but feel fine. I waited until my BG had come up to 4.5 and tried to recalibrate and got the lovely message that the sensor had expired. Great. It seems that overnight my BG was locked at around 9.5 and I got the message that I needed to give a BG due to minimum delivery? What happened to my 6.7 target? Really not loving micro-bolus. The only time it holds is if I don't eat! I"m also finding that if I enter carbs, the pump only gives me a fraction of what I expect it to. I thought that was because the MB would keep it all going, but it doesn't. And because I can't do a wave bolus, I can't split the insulin delivery. I've just had calzone for dinner (folded pizza) and I know I need a bit of insulin now and a portion later once bread has digested. I can't do this. Now I'm looking at a BG of 6.5 with 3.5u of active insulin and fully expecting a hypo (although if this is an actual hypo, or just the pump telling me I'm sub 3 that's anyone's guess.
This doesn't seem like a huge leap forward from the old pump and sensors. Annoyingly on the ANZ 670g support group I see people who have got 2 weeks plus from sensors. I don't get it. They seem totally inaccurate. I don't understand why it asks for BG all the time, but not for calibration reasons, just because?
2 weeks into this, it doesn't seem very good. I'm getting through test strips like there's no tomorrow and having to do the tests at random times through the day AND night. At this rate I'm tempted to sack off AM and go back to manual - after all, this method got my a1c down to 7.7
So will be emailing Medtronic to get 2 sensors replaced. Not a happy bunny.
(Oh, I'm hydrating well - plenty of water, been mountain biking today which was fun as the sensor was still in warm up mode for the first part of the ride)
I know people said be patient..... But I was actually happy with the 640g and its way of working.
