I'll give one word of caution on the Oral Glucose Tolerance Test.

Someone like me with Reactive Hypoglycemia (self-diagnosed as it was) should only take this test with caution. The purpose of it is to see what your blood glucose is at various intervals after consuming a very sweet drink. If you're diabetic or pre-diabetic, your blood glucose will remain at high levels two hours later. If you're a reactive hypoglycemic like me, your blood glucose will tank...which is exactly what mine did. I developed hypoglycemia symptoms while driving home.

Fasting: 80 mg/dL
1/2 hour: 144 mg/dL
1 hour: 181 mg/dL
2 hour: 71 mg/dL

This does not happen to me when I eat something like a high carb meal, just something very sugary that causes a quick glucose spike. High carb meals send me into the 170s and 180s,and I stay elevated over 140 for hours.

Unfortunately, your other links aren't working, Glenn. The websites must have restructured.

I haven't discussed my glucose issues with my neuro yet. I won't see him again until October. By then, I'll have been low carb for a year and see if anything has changed symptom-wise.
