A bit of an update on this post: I have tried Humalog as dictated by insurance here, for over 3 months. The results have been anything but stellar. My blood glucose average went from 120 (6.6) to 150 (8.3) in the 3+ months since switching from Novolog to Humalog.
I saw my GP and took a download from my pump which verified my blood glucose readings for the same amount of time since switching. My average daily carb count was about 120 and I guess there is room for improvement there. Doctor suggested lowering carb count to 100 and see if that might help a bit. I am also trying to view downloads from the Dexcom G5 sensor to see where else I can improve.
My GP applied for a special waiver for me to switch back to Novolog and insurance denied it. If I wanted to pay out of pocket for Novolog, it would cost me $3,798 USD for enough vials to last me 90 days. Be glad for your NHS in spite of any issues you might have with it. I am stuck with Humalog which clearly doesn't work as well for me. For the first time since 2003, I am struggling to stay motivated to the point of giving up.
My GP saw how frustrated I am over these changes, so she suggested delaying doing an A1C test for another 3 months. Maybe I can figure out something to turn around these numbers I am seeing on my blood meter and the downloads from the pump.
