seizures
"Keppra alone did not do anything for me except make me depressed and have "Keppra rage".  I was up to 1500mg 2x a day and would still have a grand mal about every 4 months and absence seizures in between.  My neuro switched me to Topamax, Depakote and everything else but would break out in rashes or have horrible diarrhea and every other side effect.  Back to Keppra I am 2000mg 2x a day (400mg a day total) now, weighing 175 (hell of a dose) and got put on Lamictal as well up to 100mg 2x a day of that.  1 month since addition of Lamictal and higher dose of Keppra and no seizure yet.  We shall see."
