narcolepsy
"Xyrem actually worked! For the first time in my life, I felt like a normal person. Then, the migraines to beat all migraines began. I was awake but in so much pain and the only thing that helped at all was packing ice all around my head. I hoped the headaches would go away but, after a couple of weeks, I gave up. I didn't want to be awake with that much pain."
