Buggy sensors and making them last.

In the last 2 months, I was able to drop my average glucose from over 200 to under 100. I'm really happy with my progress and my CGM is a huge part of it. And when they work, they work great. But I've been having some issues and I haven't had much luck with Abbot customer service.

My first issue is getting the sensors to last the entire 15 days. If they don't fall off early, they start behaving erratically around day 10. The back of my arm has very loose, fatty skin. And I'm worried it is like plunging the sensor into jello. And perhaps that is causing an issue.

If the sensor stays in, after 10 days, it will start giving me inaccurate readings. Often it will set off alarms while I'm sleeping. Saying I am 60 or below. But once I head to the kitchen to get food, it will jump up to 80 or 90 a few seconds later. And I will have no symptoms of low blood sugar. I thought maybe I was compressing the sensor but I made sure to lie on my other side and it still happened.

I just had my first successful 15 day sensor. I put skin tac on my arm, put on the sensor, then put skin tac on again, and covered it with a tegaderm patch. I had never done the doubling of skin tac before. So maybe that solves part of the problem.

But then I put on my most recent sensor, and it is giving me readings all over the place. More alarms of 60 or below while sleeping. But even when I'm awake, it can fluctuate up and down by 20+ points within a 10-20 minute interval.

I've requested so many new sensors. And, so far, they have been understanding. But now they are asking me to FedEx back the malfunctioning ones. I am going through a very difficult health recovery and I am housebound. I don't really have any way to get to FedEx and I'm worried they will stop sending me replacements.

Is it normal to have a bad sensor every once in a while? Could it just be my jiggly arm? And is there a more secure way to keep the sensor on my arm?
