Sunday’s food intake was more consolidated than it had been on Saturday. We stayed home most of the day, running only modest errands and doing projects.
Breakfast was a good match of insulin to food. Lunch was not enough insulin, resulting in the levels rising without dropping. After dinner, they rose further, so then I over bolused with five units. I then watched my levels start to drop quickly. To fend off a crash, I ate some chocolate and slowed the rate of BG dropping.
The most interesting feature of yesterday’s data is that I swapped sensors at about 1:30 am. When sensors swap, there’s a two hour obligatory warmup period when the CGM publishes no data. Because I usually swap my sensor before I go to bed, that gap usually happens in my sleep. The catch is that the first hours of a new sensor can also be erratic. I see this in last night’s data. It was high then it was low. It is unlikely that my actual BG levels were doing that.
By the time I woke at 6:45, it caught its stride around 120 mg/dl and started leveling off. That seems credible under the circumstances, so I think it is reflective of my actual BG level. We’ll see tomorrow morning in the recap on today if I am/was correct.
