As for using 3 units of R, I am still shaking my head. Neko was on a higher L dose than Sebastian, and never needed more than 0.5 units of R. Biscuits, on 40 units of Lantus, sees movement with 0.5 units of R. That is a little unusual, most cats on that high a L dose would be using more R.
So looking at his numbers, the very first attempt AM 8/13, I just did a drop. He did have a curve but the nadir wasn't until later and as far as I could tell, the R didn't do anything. Plus with the high ketones I really wanted him in the blues. So I upped it to .1 that night, checked the +2 and +5 and still basically saw no movement.
Next morning ketones were low so I didn't give any, I really was trying to be as cautious as possible and only do what was necessary. That night BG and ketones looked like they were rising, so I upped it to .25, checked +2 and +5 and they were higher. That day it actually looks like he just bounced off the 188.
Morning of the 15th, ketones up and BG high, upped it a little more to .5u. Completely flat all day long. Pretty much the same thing the following day, upped it a bit more to .75 and again completely flat.
So at this point it's feeling like the small doses aren't getting the job done, however we increased lantus that morning and while I knew it wouldn't have kicked in the first cycle, I didn't want to mess with the second cycle when it might have, so I held off. Same thing for morning of the 17th, I wanted to give the increased lantus a chance.
Then night of the 17th we hit 2.4 on the blood ketone meter and I was done screwing around so 2u R. Checked him the first two hours and then the fourth and then the 5th, only 40 total points of movement, still in the yellow.
Morning of the 18th, numbers were actually looking okayish, we were deep enough into the lantus increase, so I wanted to try 2u R and confirm if it did anything or not. Bit of a dip, about 50 points, I was actually pretty pleased with that. So I stuck with 2u again for that night, however checked him at +5 and didn't see much movement. Yeah, I only checked the +5 but the subsquent numbers from the morning don't really indicate a bounce.
So, morning of the 19th, ketones are looking good but BG is pretty high, 2u didn't quite get the movement I wanted, so I upped to 3u. Between being so high and the movement from 2u, I wasn't expecting a whole lot, also had an appt, so I didn't check again until +4 and saw about what I expected to, 50-60 points of movement. Keep in mind at this point I had never heard the "don't want more than 100 points drop" so I probably should have been content with that. And actually I did look back at the thread and I see where you did in fact mention that Wendy, so that's my bad for missing that. Anyways, so night of the 19th we hit purple, however I want some sleep so I stick with the 3u and check at +5 and get 199.
Morning of the 20th looks really good, 201 and ketones low. I did find it a bit odd that it seemed flat from the +5 but I let it ride. Then the 412 hits and I go right to the R. Knowing the 3u only gave me about 50-60 points of movement and I'm wanting like 200 to get him back to a "normal" level, I go with 5u. And it does pretty much exactly what I wanted to, brought him right back down to 200. Big drop, sure, but nowhere near hypo range. And since the PMPS was under 200 I let it ride that night. But I get a few more tests to see what's what.
And then this morning has been up and he probably could have done with some R but I wanted to get this all sorted first.
So, here's my thoughts on it. I don't think at any point he got even close to hypo range, probably never even below 150. The biggest gap in data that would have helped the most is from the night of the 19th, however, I still resist the "went too low" idea. If he went too low between the PMPS and the +5, why wasn't the AMPS higher? And given the cycle of the R, it just doesn't seem like there was enough time in the cycle for him to go much lower between the +5 and AMPS. I'll admit it's hard to draw any kind of curve that night so he was probably up and down a bit. But based on the couple urine readings I got from him it looks like his renal threshold is right around 200. So what it looks like to me is that he's spent so much time above it lately that even going as low as 180/190 was enough to trigger a bounce, which we can see a couple instances of over the span. Obviously we don't want bounces but I don't think he was ever at risk of hypo.
But I suppose there is one bit of info I never thought to ask about that now seems relevant, are the bounces triggered by where he drops to or by how much he drops by? If the simple act of dropping by too much, regardless of where it's to, is enough to trigger a bounce then yeah, I absolutely triggered a bounce with the 5u bringing him down 200 points in 4 hours.
And just to bring it back to my resistance to the "going to low" idea and the night of the 8/19, that's the part I don't understand the most. How people are drawing the conclusion he went too low based on that data. Like I said above, I just don't see the curve that allows that to happen, based on the PMPS, mid cycle, and AMPS data.
A sweet use of R (especially for those new to R) is to administer R at the very first signs of a bounce. It will prevent kitty from going as high as they would have without R. The bonus here is there's no mistake made in giving R when the bounce is breaking.
Honestly I thought that's what I was doing at the 412. Big jump, give the R, bring him back down.
