Well right now you have two choices up or down. Helpful huh? Either go up in dose and force him down but risk him nose diving while you can't monitor. Or reduce and pray he smoothes out and at least regulates ( 200s at preshots, 100s at nadir) and either ease up the dose from there or switch insulin. Both choices have risks. Personally if he was mine I'd go down to 1.25 see if he stops swinging, while catching as many ketone tests as possible.
