Yes I can get that too. In my experience it depends what carbs I'm having with my meal. I've discovered that vegetable carbs in particular are unpredictable with my sugar levels. Eg. I can hypo just over an hour later after eating vegetable carbs and I can equally be hyper too after eating them with the same quantity, type, and insulin dosage. I saw a dietician about it previously and I just got told well you probably should have a grain carb with your meal to avoid this. Eg. mix your carb type in your meal rather than all the same type.... still try and stick to the same quantity though (eg. don't eat too much carbs). I have to admit when I do what she said it does work better at preventing hypos. For me grain carbs seem more predictable.
