Migraine Prevention
"I was taking 6-8 Excedrine Migraine daily to control my headaches.  I saw a neurologist and was put on Zonegram. It took 1 month to build up to 100 mg per day. I was headache  free after 2 months and have been that way for 3 months now.  I will step down from the pills in 6 months. No side affects for me at all ."
