Tbh I'm not sure what I suggest lol The only thing I can see is when he's been relatively flat yellow like he was yesterday (301 is yellow if you squint), perhaps a 0.5U or 0.5U fat. It's interesting because that's a Lantus thing - flat yellow often means action to follow.
What tipped me off is I know his "typical" nadir on a non-bounce is about +6 (and I'd give him leeway to +8 ish)....so he had 4-6 hours of rising to do after that. The fact he only came up to 140 tells me he was very likely under 90, but he has occasionally shown he can have flat latter parts of the cycle.
More people are having luck with prices on the generics (semglee and "insulin glargine") and places like Rite Aid and Walgreens, even the locally owned pharmacies.
