epilepsy
"I have been epileptic since I was 5 years old. Now I am 24 years old. I started taking Keppra 2 years ago. In the beginning I was so tired and sleepy- nearly lethargic. That wore off after the first 3 months of being on Keppra. Since I have been on Keppra for over two years I only have had 1 seizure and it was because I missed a dose. But sometimes I think there are other side effects due to Keppra such as lack of concentration, frustruation, irritable and anger."
