epilepsy
"I have been diagnosed with absence seizures and have had several Grand Mals for 6 years now, but have been seizure-free for 4 years, after being put on Depakote ER.  I went through 2 prior doctors and twice as many medicines before finding the right one. If taken in the morning, I get nauseous and I'm always tired, but otherwise, no problems. 155 lb female on 500 mg once daily."
