Wow. I find this interesting. Who is monitoring your blood sugars? The reason I ask, is because I am a diabetic, and my diabetic nurse and the doctor who oversee my condition and my meds don't consider 120 to 130 "high". A normal range daytime range (non-morning fasting) is 120 or under, but 130 is not at all concerning for diabetics. at least, that is what I have consistently been told, and I do onto freak out with readings like that.
I suggest that when you supposedly feel "sick" from carbs but discover you are low at 60 (which is a horrible feeling, been there) you are actually feeling hypoglycemia and actually need to eat some protein.
I've never had any correlation between indigestion and my blood sugars; I get indigestion if I overeat, never a wise move for a diabetic.
