I had trouble explaining to my endo at my last visit why I don't always bolus prior to eating. So much trouble that I was painfully aware that she didn't have diabetes and didn't understand some of the tiny nuances that come along with this.
Lately the main reason I've delayed a bolus is because I don't always know how much I'm going to eat. And it really sucks when you think you're going to eat X number of carbs and then bolus and then wind up not eating that amount.
Sure, there are other times when I go into a meal too low to justify bolusing up front, but for the most part it has to do with not really knowing how my stomach will react to what I'm planning to eat.
