Charleston's pmps tonight was 164, which is way lower than normal for him. I fed him as usual, waited 1 hour and checked again. He is now 283. I see from the prozinc dosing protocols that I can now either choose to skip, given him a partial dose, or give him his full dose. Any suggestions of what to do? Sorry to tag you @Deb & Wink, but I would love your input. And, what would cause him to be so much lower at pmps than when I checked him roughly at his normal nadir time?
