M.L.
I get dizzy, tunnel vision, fall and almost pass out sometimes as well when I haven't had much to eat, but I'm hypoglycemic. I tested 'borderline' with gestational diabetes during pregnancy and was also told by my Dr. that "everything was fine".
Perhaps you need a new Dr. who will test your blood sugar levels.
