OK I'll give it a try here to answer you.
First, there are two tests that you need to get: before the am shot and before the pm shot. These two shots are needed to know if it's even safe to give the shots. If you test and the number is low, you may have to delay the shot or even skip the shot, so those two tests are most important. A third test that is quite important is the before-bed test. Many cats go lower overnite, so testing just before you go to sleep will let you know the number has not gone too low. Many people have been surprised by a low number and stay up to feed the number and bring it up.
Testing stress on your part is contagious, so if you are upset, kitty is going to feel it and also get upset. Make the testing a more calm and rewarding event. By just sitting for a bit and patting to calm both of you, and by offering a small treat will go a long way to associate test with treat and makes for positive results.
Feeding before the test is not a good idea because you want a true number that is not reflected by food. Many take up food for the 2hrs prior to shots because food may bring up numbers higher but for a short time only. You may give a shot to a number that is higher from the food and then find the numbers drop after to a low number. If you test and find a low number, you may be told to HOLD food, and test again in 15min to see if you have a rising number and it's safe to give the shot. If you have fed at ps test time, you will not know if the test in 15min is higher because you fed or higher because the BG is rising on its own.
So, test first, then if OK to shoot, give food and prepare shot.
Now, from looking at the ss, your dosing is all over the place, so there's no way that the insulin has been able to settle - the shed needs to fill and only then can you see if the dose is good.
If you can stay at this dose of 1u BID for 5 days as in the protocol, you will allow the shed to be properly filled and settled, and you will see how well the dose is working. Be sure to stick closely to the 12/12 shot times, and get your ps tests every time. Others will want to see more data around mid cycle to see where nadir is, and see how well the insulin is working. Your dose changes are going to be based on the BG numbers around nadir and not on your ps numbers, so when you are able, maybe weekends or something, do curves as you have been doing. Most people who work are in the same position as you... we test on evenings and on weekends. Depending on you, curves can have tests as often as you like. Every 3hrs or 2hrs is good. Eventually, you are going to see a picture emerge, you will see where she has her nadir.
After the week of letting the dose settle, you and others will be better able to tell you how to adjust the dose, and by how much.
Post daily in one thread a day so you can keep all numbers and questions together. The others can give you the specifics on that aspect, as well as linking the previous day's thread into the next day's thread. It's important to be able to look back through the days threads to see how things have been going.
I am sure you will quickly find that she does not mind the testing, especially when she is getting some nice pats and a little treat out of the deal.
