If he's still coming up with an occasional higher number, you could try him on a 0.05u dose...that's what I had to do with Rosa to give her the last little bit of support she needed to go OTJ. And yes, even 0.05u did push her down just under 50 in the end...she actually earned her last reduction even with only that teeny tiny bit of insulin on board!
I did it by pushing on the syringe while I put the needle into the vial, then releasing the pressure off the syringe so it drew up just the very tiniest amount. There's no way I could have measured it any other way...but doing it that way actually did make it fairly consistent. Even when the markings on the syringe aren't always identical (and with most brands they aren't), doing it that way gets the same amount each time.I'm new to fractions of a unit so please help me understand how a person can even measure liquid in that tiny increment? And with any consistent accuracy??
