Yes, 70 seems like a reasonable guideline. A couple of nights ago, I feel he definitely would have fallen below 60 had I not carbed him, and I'm reading some information in that FD book I just purchased that suggests that below 60 isn't within the optimal range. That said, his numbers, generally, are rarely below 70, so it seems that I'm focusing on just a few incidences of low numbers to make a decision to withhold an increase. BUT (and thanks for letting me talk this out) if I want to keep him above 60, perhaps I need to keep his dose right where it is for the time being. IDK. As most everyone knows, I had truly hoped to get Jude back into remission, but I'm accepting the reality that that might not be in the cards for him, and I need to be, and am, content with tightly regulated.
