Was taking 300mg BID for seizure disorder (complex-partial with occasional progression to generalized) but had to stop because of severity of side effects: confusion, inability to remember words, depression, inability to concentrate, increased frequency of "aura" sensation/absence seizures, fatigue, frequent migraines, short-term memory loss (seems to have been related to medication rather than seizure disorder), dizziness, flushing, "drunk" feeling, insomnia (not sure if due to drug), loss of libido, occasional suicidal thought, etc. (There are others, but because of memory/concentration problems, can't remember them!)
