On the suggestion of intelligent people here, I have started splitting my preprandial bolus. I checked my blood sugar this morning. It was 120 before anything.
Breakfast was a small slice of ham simmered in butter, and a "purple thing", consisting of one eighth of a cup of bread flour, cut with a pad of butter, mixed with a small dollup of sour cream and a splash of milk, folding in carefully a small handful of blackberries. And a sprinkle of baking powder. The crime itself was the two packets of sugar, but still listen to me.
For all this, starting at 120, I used 5 units of Humalog. Not nearly enough, but I am just starting to do this. With breakfast we had Hazelnut coffee with cream.
Thirty minutes later, I checked. It was 195, but I was not shocked. Remember, I was complaining about high numbers, and I still eat incorrectly. My wife enjoys those "purple things", and what I was trying to do is find how to use insulin to keep it manageable.
I used 4 more units of Humalog. Later I was driving in the car and checked my blood glucose after this and I was 111. It looks like eating like a fool and splitting the bolus into two actually worked. Only problem was the coffee ran straight through me and I had to stop the car to pee.
