Seizures
"I&#039;ve been on 500mg 2x/day for 5 years. Keppra controlled the seizures immediately the day I started it but I did experience extreme drowsiness and can sleep for days. People always told me I looked tired and knew I was always sleepy. I also got very moody and am easily irritated to the point where no one wants to be around me. I didn&#039;t think that it could be linked to the medication until now. It&#039;s a terrible feeling but it does control the seizures."
