Hypoglycemia can be diagnosed with a "five hour glucose tolerance test". I was tested recently and the results were normal....I did not have hypoglycemia. Many things can give us the "blahs" besides lack of adrenelin. Depression. Low seratonin uptake. "March uglies"....that I can't wait until the crocus bloom syndrone. Mono, anemia, medication side effects (over or under levels).....and the list goes on. Rita
