I saw the same story elsewhere and, as a Type 1, felt embarrassed that such a fuss was kicked up.
I'd have titled it "Type 1 forgets to bolus for large bucket of milk and gets totally expected high sugars afterwards".
It's sad if she's been diabetic that long and isn't aware that a) milk has carbs b) you need to holus for,it if Younhave any quantity, and c) that most chains havd carb info online.
I drink lattes and my sugars are fine after. I saw this as a bit of a non-story.
