Well, it's a balancing act, Lori. Cats won't follow our patterns. Yes, it would be great if they would have 200 preshots and nice green nadirs. But, as you look at other people's spreadsheets, you'll see that cats don't cooperate. You experiment, seeing what a little more insulin does. Or whether it does too much. We would like a nice smile curve, going gently down and gently back up again. (if it was an ideal world)
I think I would try your 1.8 tonight as long as you can test before you go to sleep. But you hold the needle. Do what feels right.
