I know you pumpers have your dual wave bolus, but I remember hearing some people on MDIs talk about bolusing for delayed spikes. I have a couple meals that leave me absolutely fine after two hours, but then I am high at approximately four hours when I test for bedtime. I tried yesterday bolusing an extra unit at the two hour mark. I know if I bolus more initially I will go low. I still ended up high. Maybe I just needed two extra units (It involved potatoes). But what would be the correct timing to bolus the extra? I would rather head off the high than wait and do a correction later (which is what I ended up doing).
