Goose, don't feel like your cat is the only 'puzzle'. That is often what it feels like when trying to figure this stuff out. Unfortunately, none of it is black and white, so there is a degree of experimentation involved in figuring out what works. That is why so much focus is put on getting as much data as possible through testing. You're in a rough part of it right now, but it will be worth it once we 'crack the code' and get Do Daa on track. (I like his name.

) A lot has been said about testing, but let's step back a minute and talk about what is needed and why.
Regarding testing, as has been stressed already, you obviously want to test before every shot. Hopefully, that part is beginning to feel very routine already... test, feed, give shot. The main point of that is to keep Do Daa safe. When you are seeing so many high numbers, it may not seems so important, but you never know when he could surprise you with an unexpected low number. And, besides, that test gives you a starting point from which you can then see what impact the insulin has during the cycle. The mid-cycle tests are important so you can see the impact of the dose, and again, safety does come into play. Even though he seems to always be high, a low number can come out of nowhere and testing allows you to catch it when things are heading that way so you can intervene and avoid any kind of crisis. Now, as much as we would all love to know what his glucose is every hour of the day, obviously, that is not reasonable (well, unless you got a Freestyle Libre, but that's a different discussion). So, for your normal daily testing, I would suggest doing your mid-cycle tests between +3 and +9. This is the time ProZinc is usually most active with the lowest point usually falling between +4 and +7. If you can get a couple of tests in during each mid-cycle right now while we are trying to figure things out, that would be terrific. It is important that at least one of them is between +4 and +7 - and if there is a cycle where you can absolutely only get in one test, make it during that time. I know the impact it has when you have interrupted sleep over an extended period of time. So, I understand what you are saying on that, but it is so important that we know what is going on both during the day and the night. Not trying to get too personal here, but do you get up to use the restroom during the night?? That might be a good chance to do a test without interrupting your sleep too much. If you don't, then it really is worth setting an alarm to do a test in that crucial +4 to +7 window. You can vary the time.. one night +5, the next +6, and so on, so that you begin to get a better picture of what is going on. Another thing you might consider is doing a curve on a day when you can. A curve means testing at pre-shot then every two hours (or three, if you cannot do two) up until the next pre-shot. Doing that gives you a snapshot of what a cycle looks like, when the insulin starts working, when Do Daa goes the lowest and when he starts heading back up. In my early days of ProZinc use, I found it helpful to do one at least every couple of weeks. If you cannot do one, it just takes longer to gradually accumulate enough data at different times during the cycles to figure out the same things.
That was really long (sorry), so to summarize:
Test at every pre-shot.
Test twice during every cycle, if at all possible, between +3 to +9 with at least one of the tests being between +4 and +7. Vary the times some within those ranges.
If possible, do a curve periodically.
Do you think this is reasonable and doable for you?
