Yes, then it's possible that the PS was food influenced. You might want to note in the comments when that happens. Even better if you can avoid feeding him towards the end of the cycle since feeding after the nadir can reduce duration. However, some cats cannot tolerate very long gaps between meals. In those cases, you want to feed as close to zero carbs after the nadir.I know on the 111 I he was a little short (15-20 minutes) of feeding 2 hours before PMPS. Does not waiting the full 2 hours affect BS?
I would try not feeding later in the cycle and see if that helps. Till when in the cycle does he get food at night? Do you leave food out before you go to bed and pick it up 2-3 hours before AMPS?
He seems to have lovely green AMPS-es despite eating 2 hours before. Maybe he just needs to go back up to 1.75U to get rid of the blues and bring his numbers down.
Is there a reason you don't shoot at 7:30am/pm since you seem to be up anyway to feed him? Just asking because then you needn't stay up very late to get tests in the PM cycle.
It's not unusual for cats who are making their way down the dosing ladder to pause or go back up briefly in dosing before resuming their slide downwards. See what he does with the change in meals times, but an increase might just be the impetus he needs to resume downward momentum.Really don't want to increase. Let's see what he does today. Going to see if feeding a little less and not so close to end of cycle make a difference.
