“I have had intermittent ocular migraines for about 30 years.  About 4 years ago, I found information to cut free glutamic acid out of my diet entirely and the headaches ended.  Once or twice a year, I will eat something with hidden MSG in it and get another migraine, but I have always been able to figure out where the MSG was.  My ocular migraines happen about 12 hours after ingesting MSG.”
