Migraines

DEAR DOCTOR K: I’m plagued by frequent migraines. I take medications to treat the migraines once they’ve started, but I’d rather prevent them in the first place. Any suggestions?

DEAR READER: Migraines can be debilitating. The severe, throbbing headaches are typically accompanied by nausea, vomiting or loss of appetite. Many migraine sufferers also develop blurry or distorted vision, or see pulsating lights or dark spots. Most migraines last from four to 12 hours, but they can last much longer.
