seizures
"I have spacial seizures.  I take 1200 mg per day.  It has been 100% effective for the last two years.  I had about six months of problems after I began taking Lipitor, but none since I was taken off the Lipitor.  I'm a 67 year old male who has had seizures for over 30 years.  It has been as effective as Tegretol was until it stopped working after 14 years.  I had a short bout with low sodium after open heart surgery."
