narcolepsy
"I got diagnosed with Narcolepsy about a month ago. I got prescribed Nuvigil and took it for two weeks straight. The medicine had some side effects like headaches, but soon my body got use to the medicine. I'm a college student so it's crucial that I stay awake when I'm in class, and Nuvigil helps me do that. Its effects slowly begin to work so I have to take it early in the morning."
