The biggest thing is pre-bolusing if you're going high early and low after that.

The key things are: counting carbs precisely, figuring your exact I:C and ideal timing for bolusing. If you can control these 3 things then there's a very high chance you can eat high carb meals without problems.

It's easy to over/underestimate the amount of carbs in some foods. Like the soup you had, depending on what kind of soup it can be pretty hard to know how many carbs you are actually eating and that can make it seem like your D is out of control when in reality you're just miscalculating. I avoid some foods just because I have no idea how much to bolus for them.
