Actually on TR as a long term diabetic, you would have held, though I know that Darnell has a preference for SLGS, but with being long term and a with Sproket having a recent history of DKA, if it were me I would probably err more to a TR type approach and would have stuck with 3.5u, though I do understand why Darnell wanted to take the reduction.
Darnell, I have been watching Sprocket over the last few days, and I can see how that nose dive he took the other day was very scary, I see you noted it as a hypo in your ss, was he exhibiting symptoms of a hypo when he was at 48? Usually when we refer to a hypo what we mean is a symptomatic hypo. At 48 he was only just below the reduction number for a human meter (50) and he came up pretty quick which was great, you acted promptly gave him carbs and handled the situation like a pro.


I have to say I agree with Dyanna and others with keeping him on 3.25u, he really wasn't that low the other day, he responded well to the carbs and his numbers came up (as I said above I might have even held the 3.5u though I understand why you wanted to reduce), and with recent ketones the more worrying issue is them developing again, and one of the ingredients for that is not enough insulin, the others being not enough food, and things like infection and stress can be factors as well, so with his health issues at the moment, he already has some of the contributing factors to ketones developing again, by the way, good job on checking those daily, it remains an important to monitor those.
If numbers demand it, instead of feed LC, you can feed MC/HC to bolster his numbers so that you can get enough insulin into to him to keep those ketones at bay.
Seeing as he took that nose dive by +3.5 the other day, I would probably suggest always getting a +2 for him, the +2 can be a good indicator of how a cycle is going to pan out, it also allows you to intervene early in the cycle should you see he is heading for low numbers at some speed. I found that very helpful with George, if he dropped significantly by +2 I would steer with food (HC, LC or MC, depending on numbers) it allowed me to stay ahead of the insulin cycle and in turn keep the BG's under better control.
