Just wondering why you are using "two weeks under 150" as your guideline? Typically kitties should be in normal number range, which is lower than 150. We like kitties to get insulin support as long as they safely can, to ensure a stronger remission. On TR, Pia would not have earned a reduction down to an OTJ trial.

earning reductions and starting OTJ trials.
When are you feeding Pia? With a sputtering pancreas, a small meal at +8 to +9 can help bring the numbers down. Maybe that's what you are seeing at night if you are feeding during the day but not the night.
