I’m very sorry for all your troubles of late. I know how much you love Jasper and are trying to do your best by him.
But remember insulin is a hormone, not a medication. You can’t shoot the same dose for months on end and expect the same results without checking the BG. Insulin is not “set and forget”. The way he’s been bouncing combined with the lower preshots indicates to me he has probably been hitting some lower numbers.
You should always get a preshot. He could very likely be in the 40s at PS. If you shoot without testing, especially with a dose that should have long been reduced a few times at least, you are putting him in harm’s way. If you can always get the PS and even just one other test during each cycle, it will help until things improve for you.
I would cut his dose back to 0.5u, grab some tests, and let’s see if it needs to go up or down after a few cycles unless he drops low again. In that case, you need to reduce the dose to 0.25u and let the depot equilibrate so we can see what the insulin is actually doing for him.
