Hi Liza,
I don't know if you have shot or not.
Have been thinking and debating what to do with the dose for Sandy.
Too options
1) Hold the 0.1
2) Reduce the dose to a drop
Neither of these decisions, because of the recent DKA, are without risk. You are there with Sandy, you know what you are having to do to keep him from dropping, how he is dropping, behaving etc. So I will try to present you with our thought process to try to help you to come to a decision.
Holding the Dose.
The problem with holding the dose is that he may indeed drop again.
I'm not sure if when you shot the 0.1u in his previous cycle if the drop you saw was the insulin or a combination of that and the dry/temptation snacks working out of his system/or the depot from the 0.25u still having an effect (upto 6 cycles, diminishing with each successive cycle)
Now that you have removed the dry as a regular food, his insulin needs may have diminished, I am wondering if that is why you may have been struggling to keep him from dropping.
If you held, and he dropped again tonight, would he eat, the big question? You mentioned that he is always, up to now happy to eat dry, so maybe if he drops into the 40's again, you could give him a tablespoon of dry food, it's very high in carbs, and you have other tools such as syrup to give you a more immediate bump should you need it, while the dry gets absorbed.
I would avoid the dry/temptations unless he has dropped below 50 again and you need him to come up and stay up.
Feed him the MC as his pmps, and HC for his snacks at ?+1+2 +3 if he doesn't give you a food bump at +1
I can't guarantee he will not drop and that you will have to work hard to keep him safe, so you need to assess whether you are able to do that for him tonight. I wish I was there so I could physically support you with this
Reducing the Dose.
The recent DKA puts him more at risk, if he isn't getting enough insulin and he is not getting enough calories, we only have to add in an infection/inflammation/stressor and it could be a recipe for a relapse.
It really puts you in a tough position.
It's good that he's been eating in the previous 18hrs or so, and that he is still negative for ketones, and has been since he came home. Those are positive signs.
If he has been acting lethargic or seems like he is not well, then that would make me more nervous about taking the dose down.
You will need to stay on top of those ketones, perhaps checking that a couple of times a day at the very least, they can develop very quickly.
You still need to make sure he is eating well, perhaps even more so with taking the dose down. Since lack of calories and lack of insulin are both precursors to DKA.
I would suggest taking him down to a drop dose if you want to go for this option.
