Yea, I've had reactive hypoglycemia a few times....not sure how you could make a case that it doesn't exist since it's well documented in my opinion. In my opinion you came off low carb too quickly and aren't very efficient at using carbs as you otherwise would be. I'd ramp it up slowly (the carbs) in exchange for fat if you could do this all over again. Right now I'd be looking at lower the carbs just a touch for the moment, then adding a bit of MCT's, butter, or coconut oil in for some fats at each meal. I'd also make sure you are getting a good whack of fiber each meal.
