Dx3 gad you like it. Abt the itching; try different had tape, like tegederm etc, I had the same problem and switching brands helped. The stomach is the worse place, dunno why they always train on that area, it’s so annoying!
You don’t have to wait 6 hrs for the next calibration, anytime before works too. I’ve even read somewhere that calibrating 3x in a row 5 min apart at startup improved the accuracy since the sensors algorithm uses an average of the last 3 calibrations…
Wishing u lots of luck, theres a big learning curve….
