no high carb is needed yet, only when BG is going too low.
the lantus is just doing its job, took like 6-7 days and than we started seeing blues too.
i gave half a dose when it first happen and even gave a half a dose when it was over 150 but, under 200 just to be safe since we were new at this but, our diabetic specialist told us to shoot full shot over 150, half shot 100-150 and no shot under 100. since you are not going to be home, i personally would shoot a half dose if PM is between 150-200 and no shot under 150...but, that's just my opinion, there are more experienced folks on here that may think differently and offer better asvice.
the zobaline actually made my cat's number climb upwards some so i don't think his numbers are lower because of it at all.
