I know the general rule is not to correct a high BG too early, and 2.5 hours is "too early" according to my CDE (and my endo prefers 3 hours).
But surely, there must be situations where a PWD should break this rule... Right? What if you dined out and had a combination food that you had to guess on, and an hour later you're looking at an insanely high number that you know clearly means you guessed wrong? Or what if it turns out your infusion site leaked (even though you don't know how much got into your system)? Or what if your BG gets just plain too high?
Under what circumstances would you break that time limit rule?
(This is inspired by the fact tht I'm sitting here staring at a 258 on my Dexom, about an hour and 20 minutes after eating brakfast. This particular sensor has tended to exaggerate in general, but I tested at about the 1 hour mark and it was 211... So it's probably not much better than what Dex shows.)
