Donaleen,
This may, or may not, help. It's a novella I posted in PZI a year and a half ago.

Back then, we were also getting input at times from Dr. Lisa on one particular case where she had done prior phone consults with the caregiver (Lori and her kitty, Copper). Here's what she said in one of Lori's threads to help us understand something critical - that we only have control over
some things. I think I mentioned this in one of your condos a couple weeks ago. We can control how much, and when insulin, and food, goes into kitty's body. But that is only a small piece of the puzzle. What happens after we shoot and feed, inside kitty's body, is pretty much out of our control...
...Yes, it would be great if we really had *that* much control over the disease process but we don't.
(Lori - I am hoping that the last statement will take pressure off of you - not add to it. Copper's body is in charge and we are just along for the ride...doing the best that we can with the ability to affect only a few pieces of the puzzle....ie....diet, insulin, constipation, body weight - in the case of an overweight cat.)
Serum glucose, at any single time point during the glucose curve, represents the sum effects in the *rate* and *amount* and *timing* of:
*Exogenous insulin absorption
*Endogenous insulin production
*Intracellular uptake of exogenous and endogenous insulin
*Insulin degradation and elimination - different for exogenous vs endogenous
*Intestinal glucose absorption
*Endogenous glucose production
*Tissue glucose uptake and utilization
and then throw in the amount of exogenous insulin....excess body fat....inflammation....subclinical infection....etc...etc....
....and then add in Copper's recent bouts with constipation (stress => increased BG) which prompted an email to Lori to get Miralax (or generic PEG 3350) into him asap before he ended up needing an enema at her vet's office...which is not easy for her to get to and I hated the thought of Copper having to go through all of this. (Dosage Rx was to start with 1/8-1/4 tsp AM and PM - mixed into food - and dose upwards to effect.)
Another thing she said, and this goes to your point about how Ozy was responding in September compared to today.
(paraphrased)
"Ozy isn't the same cat today as he was in September. And he won't be the same cat in November that he is today."
From that, I came up with this, that I use on occasion:
Don't assume that what worked last week will work the same way this week.
And don't assume that what fails this week will fail next week.
When treating diabetes, you're sort of shooting at a moving target. Things change daily.
