7 years for me to go to catch up with your 61 years on insulin Vic but I had to smile at your description of needles like shotgun barrels because I remember them well.... and occasionally boiling them on a stove when I thought they should be sterilized.
From what you said it seems as if your insulin does eventually kick in. I'm using fiasp insulin which should be even quicker than Novorapid but my extra boluses don't seem to have any long lasting effect. Had a long conversation with a nurse at the firm who supply the Medtronic pump. Have now swapped canula placement from stomach to thigh, which I haven't used for ten years and that seems to be working ; no excess blood sugar since.
