A patient describes her multiple sleep latency test experience, diagnosis, and treatment to Business Insider.

Here I am sleeping in the corner while my girlfriend’s friends play Taboo.Several months ago I shot up in bed and starting screaming. A mild leg cramp had made its way into a bad dream that started to evaporate even as I yelled, “Ahhh, ahh, ahh!”

My alarmed girlfriend also popped up next to me in bed. “Leg cramp,” I said, sheepish and confused, with my heart racing. The next day, I finally made an appointment with the NYU Sleep Disorders Center. Much later, I would get a diagnosis from a sleep doctor that I didn’t expect.
