So you know that little orange tab thingy you have to snap off that prevents the insertion button from firing? It turns out that if you’re not careful, when you snap it off you can accidentally press the button and fire your sensor across the room, where it will (according to quantum effects first described by Niels Bohr, if memory serves, though he was experimenting with buttered toast) land face down and demonstrate that yup, that new adhesive is pretty good, at least on bathroom tile, though linoleum might be similar.
It would take further experimentation to nail this down, but I’m guessing that the likelihood of this happening increases inverse to the number of sensors you have left, i.e., it’s at a maximum when it’s your last one. Other factors may be included, such as the sensor you’re running now, which you just rolled over to a second session, has suddenly started giving you that painful zing! from the filament contacting something down in the muscle sheeth or whatever that really REALLY doesn’t like being touched. And it’s a weekend so you can’t get a new one for a couple of days minimum, even though Dexcom was nice about FedEx’ing a replacement right away.
Anyway, be aware, be safe out there. And don’t cross the streams. It would be bad.
