Lori, I'm so sorry for your loss. :sad:
Ok, that data helps. It also changes my thinking about what is going on, about the nadir being late. Now I'm thinking that the 128 late in the cycle was him coming down from a bounce, not a nadir.
It looks like he got a big drop early in the cycle, then he zoomed up. That 76 is a nice number, but it's a big fast drop, and his liver is dumping sugar to protect him from a hypo event. It may seem paradoxical, but if you are giving too much insulin, you can see higher BG #s. We want to get a nice even curve, not a fast drop and then a zoom to high numbers. Less insulin should help even it out.
I would try lowering his dose to at least 3.0u, (and personally I would like to see an even bigger reduction, maybe 2.5u, for safety's sake...but I am conservative) and keep getting as many numbers as you can and post them. You're doing great! I know it is hard to test all of the time and have a life, just do as much as you can. :smile:
There is a PZI insulin support group, you might want to post a thread over there too, to get more eyes on you numbers. I'm going to post a link over there now, so others will take a look at your data. There are people over there currently using your insulin, and can also give you more input. More opinions are better! You should also look at the threads over there, it will help you learn. I know you can't make a SS with the Wii, but are you able to view other people's SS at all?
