Hang in there Caren (and good job on the new post



).
Nothing alarming, just bouncing - here is info on bouncing from
The Basics sticky - a bounce can take up to 6 cycles to clear.
On the day of the surgery if the dose was held at 1., then yes it would be .50. Yikes, .25, I would be a nervous wreck, and I'm a pretty stable person, except when it comes to cats. Another question I wanted to ask regarding the withholding food. Apple's 12 hour cycle is 5:00 a.m./5:00 p.m., if food is withheld after 10 p,m. or midnight and surgery is 10:00 a.m. the next morning, is there anything to be concerned about with that. The reason I ask is the vet that called for the full dental removal said that no one in this little city was capable of the dental work and to drive 4 hours r/t and pay $5,000. to a vet in Pittsburgh. So when I found a vet in town, for a lot cheaper, there's this seed planted that I should be Leary, which isn't cool.
If you decide to switch to TR, the earliest you would increase is tomorrow morning and it would be to 1.25u and hold for 6 cycles before increasing unless a reduction is earned - you'd take reductions for long-term diabetics (1 x under 40, 7 days between 50-100, or you can try reducing 3 x under 50). And by tagging, Wendy, she'll get an alert (though sometimes the board is a bit quieter on the weekends

).
Are you saying your vet wants Apple regulated and down to 0.5u? Or are you saying on the day of surgery, give a half dose? If it's the former, IMHO, the size of the dose shouldn't matter - I would think the vet should be looking at the overall BG numbers, regardless of the amount of insulin. If it's the later, on the day of surgery, a token dose is often okay - those with more experience can help advise when the time comes - fwiw, Jax was on 1.25u at the time of his dental surgery and I gave 0.25u the morning of his dental (and then skipped his dose that night since he was still pretty drugged up...ECID). Perhaps Wendy can weigh in on that comment too if she stops by since dental issues directly impact BG.
You're doing great and Apple is clearly very loved
