All sounds good, wholesome early-pump-days Donald! Before long you’ll be able to do set changes in your sleep and you’ll probably find the incidences of set failures will decrease. However, I guestimate that one in every, mmm, 15-20 sets goes wrong. I wonder what everyone else’s failure rate is?
Anyway, I had loads of “oh shit” moments when I started on the pump – with high BGs galore! But it’ll get better!
