It sounds like you need to look at the number of carbs it does actually take to
raise your blood
sugars, and even what you use to
treat a low. One thing we do for lows is to
have our daughter take glucose tablets. They are 4 grams each, and raise blood sugars about 20 points for her. 16 carbs of yogurt would raise blood sugars into the 200s for our daughter, so you are likely just consuming too many carbs.
