Yes, you went from 5.25u to 5u for 4 cycles plus a reduced dose of 4.75u one cycle, a skip and increase to 5f. That’s a lot of dose hopping in such a short time especially with SLGS
I’m not sure why you shot 4.75u PM 6/14. Since he’s been diabetic since last Dec, it would have been ok to shoot 5u. On PM 6/15, you skipped because he was at 74. I would have stalled a bit without feeding to see if he came up and then I would have reduced to 4.75u because he dropped below 90. But then you raised to 5f? Then you skipped again because he was below 90 (again, a stall might have helped) but didn’t reduce to 4.5u on the AM cycle 6/17.
I would definitely reduce to 4.5u the next shot. If he’s 90 or below, try stalling without food, testing every 30 mins, and shoot the rise. I’d stick with 4.5u just because he’s got a 4.75u depot going.
Moving forward, try to stall without feeding and see if he comes up so you can shoot within a two hour window. We never stall more than two hours. If, at any time, he drops below 90 again after this current cycle, reduce the dose by 0.25u.
I hope that helps. Remember, consistency is best as long as it’s safe.
Hope you get some rest.
PS: it’s not a hypo unless he’s symptomatic. Has he been? If not, it’s best to not use that term even though 40s are low on an AT.
