extreme dizziness!

I have just been diagnosed with hypoglycemia and the worst part of this is the dizziness. How do I combat it? Even though I have gone to eating small meals or snacks every hours I still become dizzy on the third hour..even if I am already eating again. This is scarey since it happened the first time while I was driving. My husband had to pull the car over for me. I need to find a way to decrease this symptom.Others that have advice please advise!
thanks
Lynne
