I got a box of IV 3000 tape a couple of weeks ago to keep my CGM in place. It tends to bounce around without it.
I really think that it is a defective box or something because every time I take a shower the tape bubbles up and starts peeling off like snake skin. So, I proceed to put another piece of IV tape on top of the other one.
The next day I take a shower AND... the same thing happens the tape starts to bubble up again. But this time by the time I notice my shirt is sticking...
