Kimbra---what they all said about having a normal BS and sometimes still having hypoglycemic reactions (symptoms) is true. Mine is very often normal on testing. The way I found out is years ago, when I worked in a doctor's office, I was always running out of gas, getting faint and jittery and fuzzy headed a couple of hours after the lunch hour---especially if I ate a very high carb-only lunch. Like grabbing a sweet granola bar. So---one day when it happened big time (everything was getting black while I was taking history on a patient) I went down a picked my finger and tested myself (lucky to work at an office)---my BS was 51. So--I knew. I have never had 'treatment' for this, I just know that if I have carb-with-no-protein, or straight sweets, and no protein with it, I am going to feel like crap within a 1/2 hr.
So, I eat as clean as possible, sort of the way Cathe says to. I can eat things like they say above, like oatmeal because they are higher glycemic (whole foods) and i often will have milk or soy milk with it for protein.
