"Been on Keppra since 12-2008 after having my first and hopefully last seizure in my sleep. It was horrible I hear. I was hospitalized for a week not knowing what happened or where I was for 3 days. The doctor said it was just a bad seizure. So far after being on Keppra I don&#039;t know if it&#039;s to soon to tell if it&#039;s working or not but I will continue to take it (very mild side effects)."
