I always prebolused when I was using HumalinR® and I always prebolus Humalog or Novolog in the AM…my BG is never low in the morning and if buy some chance it is…it’s not for long…
Depending on what my BG is doing I may start correcting 1.5 to 2 hours after my meal bolus, my BG is always changing…it’s a perpetual roller-coaster even when I’m fasting it goes up and down and I need to do small corrections to stay between my targets. For me any food that has any nutritional value is going to add to my TDD…Carb or no carb I still need insulin for any nutritional item…
