I got up to give Kitty some meds and saw this post.
It is VERY DANGEROUS to shoot Prozinc at intervals less than 8 hours apart. There are very few that post in the forum that shoot at 8 hour intervals, and that is only an option after gathering a lot of data. I have shot at 8 hour intervals for months now and am still very cautious with it.
Prozinc is a 12 hour insulin and you should NEVER dose twice during a cycle. I looked at your spreadsheet and it appears you shot a second dose of Prozinc at +5 of your last dose. Even when people do shoot at 8 hours, or less than 12 hour schedules, they test to be sure the number they are shooting into is rising. I doubt you shot into a rising number tonight. In reality, you have shot 3 units into Robbie, because at some point during this cycle you most likely will have the potency of all 3 units active. You need to test him tonight and be sure he is safe. The potential is there for him to go into low numbers quickly.
Tomorrow---Your next dose should not be given again until 12 hours after your last dose. So, in the morning--disregard your "normal" shooting times...you need to shoot at 12 hours after the last dose you gave tonight.
I hope this makes sense, as there probably will not be many people on tonight to respond.
