I went to eat at my sister's house this evening and I knew we would be ordering pizza. She also ordered a double stuffed sub and a chef's salad. The sub & salad was split 3 ways and I had absolutely no idea of how many carbs there was in my portion of the sub. I just took a guess at the amount of carbs and based my Novolog bolus on the guess. I made sure I checked 1 hour post meal to see how far off I was. I wasn't even close. I had to take a correction bolus. We can't possibly know the exact carb amount in a situation like this. Would you have had the sub, not knowing the carb amount? This doesn't happen very often but I do feel like the oddball who can't enjoy a simple sub.
