Blood Sugar "Morning-After Pill"? - Nothing mysterious

Nothing mysterious. 120 is just an arbitrary value selected for a maximum. You could use 100, but that is about as low as I like to go due to heart concerns (But I was 84 this morning and that is just fine). My endo uses 120 in his version of the "add" formula for pre-meal adjustment to background BG. My reason for asking about PP numbers is that since I am new to insulin, I just did not have a feel for what could be expected of insulin in the way of PP compliance.

Really, 120 should be your max target. Excursions higher after meals may not be avoidable, but 120 is sort of considered the magic number. I'm not sure that I understand this, Syd. You've mentioned in several messages regarding your insulin use that 120 is your 'target bg' that you correct DOWN to -- are you saying that you not only correct 'down' to 120, but also don't want to go any HIGHER than 120? I'm wondering if that plays into what you were asking the other day about how high you would expect to see a person be elevated PP? Because there is NO way that insulin is able to stop ANY rise in BG from occurring, even if the insulin to carb ratio is set correctly. Personally my correction target is 100, and if I'm higher than 100 I correct down to 100 and add that into my pre-meal dose. If you're starting a meal either AT 120, or higher than 120 and adding insulin to that meal dose to bring your BG DOWN to 120, you're already playing with variables that will result in your being higher than 120 1 and 2 hours post-meal.
