Today at +8 he was 305...I know for sure at +9 he wiil be red ..that means, if i wait, at least 6-9 hours of glucose toxicity,
till the +12 shot takes effect.
I gave him a shot (reduced) at +8.5 (tried to wait), and now 3.5 hours later he is blue(166). I saved his liver 8 hours of poisen.
that's how i see it.
how many of us can really wait around till +12 in this situation? would you?
What I'm saying is that, from my understanding of the way long-acting insulin is designed, I don't think the blue number you saw tells you that you saved his organs from damage for eight hours by giving the reduced dose 3.5 hours early. I think the shed did that based on shots you gave him several cycles ago -- unless Levemir's shed action is totally different from Lantus' shed action. Nonetheless, they both have sheds, and they are supposed to use those sheds to regulate the BG, NOT regulate the BG through the shot that you gave immediately before you see a Blue (or Red, or Yellow, you name it) number.
I think the only way you could know that you cat's body is sooo different, and is using Levemir in a unique way that makes your actions make sense is if your cat had a continuous glucose monitoring device that graphed a curve for you in real time. I also think that if your cat had such a monitor, you would see what the Levemir really does, and you would see that you are actually bouncing your cat's BG around in a way it would it not be bounced if you were using a 12/12 schedule.
The concept of the shed was very, very hard for me to grasp because I was resistant to it as you are. You are definitely not alone. I think that if my cat had not been a bouncer, I would have understood it sooooo much earlier, and that my anxiety and fear of his high numbers was getting the way of my brain working properly to understand. I gave him one, only one dose, at 1 unit, saw a high number, and couldn't stand to take the risk that going up in dose was the appropriate thing to do instead of holding the course at 1u for a while.
I couldn't stand to wait for 3 or 6 cycles to find out. By complete accident, I may have done the right thing, but it could have gone the other way. I say "may" because I found out later that glucose toxicity had set in (most likely) and going up was the only way to go. However, if GT had not yet set in, and it actually happened a few cycles later while I was going up by .25u until I got all the way to 2.75, it is possible that that 1u dose may have worked. I will never know for sure. This is why it is recommended that you drop to 0.5 or 1u and start going up slowly based on data that you get from shooting every 12 hours no matter what numbers you see until you have held the dose long enough for it to settle. In the end it takes less time to get to the right dose! (You just have to test for ketones religiously, and you are home. So, you can do that.
In any event, I think that if you cannot believe or feel comfortable using Levemir the way it was designed to be used, you should talk to someone who has used a different insulin and see about switching to one that lets you determine the dose based on the Amps and Pmps BG reading. I am not saying give up on Levemir, but you need to explore the idea of using a different insulin at least. It may, at the very least, help you understand the shed concept better, and if necessary you could use the other insulin for a while until your cat stops bouncing. You could possibly come back to Levemir later? I hope that it helps you to understand the shed and trust that the protocol is the right way to use Levemir whether you stick with Levemir or not.
I also hope others who know about Levemir and the other insulins besides Lantus will chime in here with thoughts about my suggestions.
