seizures
"I have taken the drug for about 6 years with positive results for seizures.  The seizures have subsided to about 1-2 partial complex seizures per month.  I do go through periods of depression, especially when the prescibed amount is changed.  I'm currently taking 1200 mg in the AM and 1500 mg PM.  It's probably the best seizure medication I've taken to date, and I've been on almost all of them at some point in my life over the past 30 years or so."
