epilepsy
"I have taken Keppra for the last 8 yrs. I take 6-500mg pills and 3-100mg pills a day. It has worked very well for me. I did have a Grand-Mal Seizure a few months back. It was the worst I ever had. They did a blood level on me and my blood level was Therapeutic, Meaning normal. It is a good medicine to take. But like any other medicine it has it's off days. I do recommend it though."
