Thanks, Glenn. I'm doing a lot more reading on this.

For what it's worth, my fasting glucose is always in the low 80s and my A1c in the low 5% area. Neither fall in the range of even pre-diabetic.

Earlier, I found this seemingly good article by docs at the Cleveland Clinic.

"Research findings strongly suggest that even prediabetes is a risk factor for small fiber neuropathy, and that so-called “impaired glucose tolerance neuropathy” may represent the earliest stage of diabetic neuropathy."

I've already set about changing my diet to a "diabetic diet." While I'm only slightly overweight and generally quite active, I have had a tendency to have a high carb diet that, while low in sugar consumption, is high in whole grains. I'd go days without eating meat and be perfectly content.

I'm working closely with a good friend now who is a severe diabetic after having had most of her pancreas removed. She has done a ton of research, and has been helping tremendously with supplement information as well as diet recommendations. She has also recommended "Dr. Bernstein's Diabetes Solution" book.
