I think something you might have missed out on is that R-type insulins have a second release coming at the 1.5h to 2h mark where, if you look at the chart I posted earlier, the insulin truly peaks. Your carbs should cover the first peak, so you have your food (your sugars and your proteins), then you go train. Right as the second release comes around you want to eat again; some carb powder like Vitargo or dextrose with your whey isolate. The reason why you're having the hypo moment is probably because while you covered your bases with the first peak, you neglected to eat again on the second peak. Hope this helps.
