Is it possible that you have hypoglycemia? I was diagnosised with hypoglycemia after taking the 3 hour Glucose Tolerance Test(it didn't show up on the usual 1 hour GTT). I experience the same light headedness problems in the morning or when ever I go for a few hours without eating( or after eating something sweet). First I feel great in the morning but if I don't eat for an hour or two once I awake, I feel lightheaded. If I drink juice or something sweet, I feel great at first but then I will feel lightheaded because my blood sugar drops. My Nutritionist & Dr. recommended that eat protein in the morning( and protein snacks in between meals) because it keeps my blood sugar level instead of the the ups & downs. This works the best for me. Good Luck.
