Seizures
"I have a brain tumor. I&#039;ve been on 1500mg/day since Feb 2011. I had a gran-mal seizure in the middle of the night. First seizure, first indication of the brain tumor. Haven&#039;t had a seizure since. Radiation took care of the tumor. Have not experienced any of the side-effects that most other people comment on other than occasional constipation. My dreams seem to be more vivid and realistic than before.  I&#039;m 50 in two months."
