My TIR has greatly improved since going on bolus #insulin. I'm still limiting myself but I'm also going outside my doc's prescription given the amount of insulin actually dispensed from the pharmacy.
I suspect if I completely adopt carb counting dosing my TIR will significantly improve further. So I plan to discuss skipping sliding scale with doc.
I've also managed to start dialing back my basal insulin. I'm suspecting my TDD won't be that high.
