Hi Sandy. I'm Dyana, and I can be here to help you with the R tomorrow morning at AMPS.
For a little history, since I know you don't know me from Adam, my kitty J.D. was diagnosed in 2005 and I started posting on FDMB in 2008, two? forums ago, I think. J.D. was not a high dose cat, but I did sometimes use R for him as he was a big bouncer. He passed in 2014 (after 9 years of being diabetic, at 20), but I still log into FDMB 2 to 10 times a day (mostly 2) just because this place becomes kind of like a family
As Wendy mentioned, you never want to accidently confuse which insulin is which. The rubber band is a good idea. I used to keep my Lantus (or later Levemir), on the top shelf of the refrigerator and my R insulin in the door. The R was in a vial in it's box, and the L insulin was in a pen or cartridge. Sometimes, we become sleep deprived or have distractions, and an accidental mix up of the two insulins could be disastrous. I used to take out my L insulin and measure the dose and put that syringe on the counter and put the L back in the frig. I would then take out the R insulin, measure the dose, put that syringe on the counter, and put the R in it's special place.
You will be starting with a teeny dose of 0.25 units to see how he reacts. I know you're not used to such small doses, so here is a picture of what 0.25 looks like in a syringe. It will feel like nothing or next to nothing going in when you shoot.

R usually has a quick onset but does not last very long (around 4 hours, sometimes a bit more). You will need to test every hour for the first 4 hours (and maybe longer), to see how he's doing.
The timing of when to give the R dose is important. You never want the two nadirs of the two insulins to overlap at the same time. If you give the R at the PS time, it should be out of or close to out of his system by about +4. If you are using Lantus and it's nadir is around +6, then you are good because the R has done what it's going to do and is done.
When J.D. was bouncing really high, I used to sometimes give R around +10 too, as it would help to bring the numbers down a little and be out of his system by +2 of the next cycle (4 hours after shooting the R) just in time for the Lantus to onset at +2 and then the Lantus could more easily do it's job.
An example of the two nadirs overlapping would be if you were to give the R at +4 and it was working full force (from +4 through +8) when the Lantus nadir hits around +6. That's overlapping the nadirs and you don't want that.
0.25 may not be enough, but it is a safe starting point.
You'll want to add the R dose and when you gave it to your spreadsheet.
This is an example of one of my PSs on J.D.'s spreadsheet.

Just to let you know there is this weird phenomenon where sometimes giving R in one cycle, will for some reason affect the numbers in the following cycle.
I work a ton of hours so will only be around for the one morning cycle for you tomorrow. If you need further help, for other cycles, make sure someone is there to help guide you through it.
I'll see you in the morning. Let me know when your AMPS is due.
