I have kinda been avoiding answering this question because it kinda makes me feel defeated... but I still can't seem to drive. I can probably drive (round-trip) about 15 minutes but after that I start to feel a little dizzy, lightheaded. I live in the middle of no where so driving 15 minutes is useless - I really need 45-60 minutes, roundtrip to go places. I have to bring food with me in the car when I go places - seems like its a hypoglycemia issue to me because the food helps. I don't understand it?
