So I've been tracking Jester's BG pretty religiously for several weeks now. Because of financial limitations, I've mostly been testing AMPS and PMPS with some occasional forays into mid-cycle tests when his AM or PM numbers seemed to justify it. He's gone as low as 53 (yikes!) and as high as over 500 (his highest since he was diagnosed) during all that time. The last few doses I've been keeping him on .5U on the advice / suggestion of someone from the main board because his BG has mostly been in the mid to upper 100s. But between yesterday morning and this evening he climbed from 180 all the way up to 415. I finally upped his insulin to 1U tonight and will check him again hopefully at the +5 point (that'd be about 1:30AMish - *yawn*). So what the heck do these numbers tell me? And what should I be doing differently to keep him on a more regulated path? I know this is a marathon, not a sprint. But why do his numbers jump all over the place like this when nothing else is changing?
