9:20 pm 20.8 mmol/L At this point I "peed on a stick" and had a trace of ketones (0.5mmol/L), so I corrected with 3.0 units
10:20 pm 26.5 mmol/L
11:50 pm 15.4 mmol/L
1:00 am 13.2 mmol/L
This is exactly the pattern you will see when treating ketones! I was excited to see this (not because it meant I had ketones, clearly) but because it is interesting and it was nice to see a predictable pattern after a day of unpredictable numbers.
The spike (26.5) occurs because the insulin has to first metabolize the ketones in the blood (this is why it takes more insulin to get back down to normal range) before it can begin acting on the sugar in the blood. I'm exhausted after an afternoon of struggling to get my numbers at least close to normal, so I'm leaving the 13.2 now and going to bed!
