--on this forum will bring up a number of links I have to lists of similar articles on neuropathy afflicting those with "merely" impaired glucose tolerance before frank diabetes.

Reactive hypoglycemia is quite frequently a precursor to impaired glucose tolerance. It's good to hear that at least your fasting glucose in quite good--but the logical question is what fasting insulin levels is it taking to keep it there. Quite frequently an insulin resistant person needs to produce a good deal of insulin to hold blood glucose levels in a "normal" range; as the beta cells of the pancreas tire and wear out over years from this activity suddenly one can get big glucose spikes, and impaired levels can happen seemingly overnight.
