Hi. I'm glad to hear that Kallie is feeling better. It is great that you are doing a pre-shot glucose test every time; however, without any mid-cycle tests, it is not really possible to know the impact of the doses you give. If you grab a test or two during any cycles when you can be around to do so, and if you vary the times you do it, you can begin to get enough data to get a picture of what is going on. Some people like to do a curve periodically which means testing every two hours from pre-shot to pre-shot. This lets you get an idea of when the insulin begins to take effect (onset) and when Kallie goes the lowest (nadir). That kind of data is VERY helpful when you are trying to make decisions on dosing. (Dickson is right, averages of your pre-shot test results are not really useful.) Ideally, you do not want to give just one shot a day. If you find that one pre-shot test result of the day is consistently high enough to give insulin but the other is not, the dose is probably not correct. It is better to give a lower does and to be able to give it consistently.
I see that the spreadsheet you are using is the one for human meters (has <50 for the lime green) but your signature says you are using the AlphaTrak2. So, please confirm that you are indeed using the AlphaTrak2. This matters because the numbers will be lower when a human meter is being used. Your numbers the last couple of days with no insulin look pretty good; however, they may still be a little bit high to just stop with all insulin. Personally, for Mia, I do not like to see 150+. I prefer to see between say 80 and 140. (I use an AlphaTrak2.) You really have to learn how low a pre-shot number you can safely give insulin on by trying things and monitoring. Having no mid-cycle data at all makes it hard to even attempt to guess at what the impact might be.
If you are prepared to monitor for a few days and to intervene (if Kallie starts going too low), if you get a 200+ pre-shot result, maybe you could try a dose of no more than .25u and hold it consistently for a few cycles UNLESS she goes too low on it. Hopefully, others will come along to give their thoughts as well.
