Today will be interesting, and I'll be curious to see her PMPS. You have a bit of a dilemma, because you are using an AT2 meter. Normally it would be suggested (as copied from the information page): OTJ TRIALS: Prior to starting an OTJ trial, one wants to see kitty mostly in the range of a healthy cat (50 - 80 mg/dL), but under 100 overall... with only occasional readings in the 100 - 120 range.
Remission is achieved when kitty can go 14 days without insulin while maintaining normal blood glucose values under 100 overall. Most will stay in the 50 - 80mg/dL range. Although, some will occasionally experience BG numbers up to 120 mg/dL.
The issue is that these ranges are with a human meter. There is no way to correlate between the two, but having some experience using both meters, I have a sense that even the blue numbers you saw last night (PMPS 128 & =3 116) would have been green on a human meter.
You have a bit of a special case I think, in that now that you have controlled those crazy bounces, she is actually looking really good. But my only question is has she spent enough time in green to give her a really successful remission. It would be nice to try a drop dose for a while just to give her pancreas a bit more support. So to me, you have a couple of things you might consider: since you have stopped dry altogether you can try TR, and you test enough, that would allow you to take reductions at a lower point (68 on AT2). That said, what do you think about getting a human meter, so that you can really see how she is fitting in with the suggested ranges as noted above? That way, you would take a reduction under 50, and shoot anything above 50.
Again, with SLGS you don't shoot under 90, but if she is above 90, you can give a drop dose.
Hopefully others will offer their thoughts as well.
