Yes, I do think so, Shannan. I actually like what I've seen on the 1.5, and if you are able to continue getting mid-cycle readings like you did last night, during either the AM or PM cycle, I think we can find a dose that works.
Right now, I think most of the really high numbers on the SS are the result of bounces. I say "think" because I can't say for sure, because I'm just assuming some of the lows that aren't on the SS.
I think the key to figuring it out is to keep things as much as possible, consistent while testing. That means you have to keep what you "put in" to Jean Luc consistent. The only 2 things we really have control over are the dose, and the food. If he eats about the same amount of food at the same time each day, then the food is a "constant". If you dose the same for several days in a row, then that is also a "constant". What you have no control over is what his body does with this stuff once you give it to him. That's totally up to "him". And that's why the tests are critical....so you can see what he's doing with it.
If you can get several days of cycles that follow a pattern, then you can adjust the insulin based on those numbers. I'm not saying you have to stay up all night, test all day. You don't have to run curves every day. One day you could get a +3 and a +9. That night you could get a +5 or a +8. One day you could get a +6. Eventually you have a "curve", just spread out over 3 or 4 cycles.
Whether you dose once, twice or three times a day, you still have to be able to determine the "pattern". If a pattern emerges, the dosing becomes a lot more simple. You might see a pattern that indicates that if you feed on a different schedule, you can control some of the ups and downs with food. Or it might make clear that something like a sliding scale makes sense.
Basically, I'm an optimist, and I'm stubborn. So I always feel there a way to do this that will work on every cat. We just have to find the way that works for Jean Luc, because it won't be the same thing that worked for Bob or any other kitty.
