migraine prevention
"The first few months being on this drug, it did not work at all. Before taking the drug I would get approximately a headache every other day and a migraine once a week. This continued a couple months after starting the drug at 10 mg. Now, after being on it for 6 months, it is working wonders. I have only gotten 10 headaches in the past 90 days and 1 migraine."
