epilepsy
"I have had grand mal seizures since I was 9 years old and was involved in a car accident. I have taken Dilantin for over 50 years, with good results. It has controlled my seizures pretty well until recently. I was diagnosed with COPD 2 years ago, and in that time, I have been having seizures every 3-6 months. My doctor switched me to Keppra 6 months ago, and in that time, I have had at least 1 seizure a month. I think it's time to switch back to what works."
