anxiety
"I have epileptic seizures & there are times my mind thinks non stop even in my sleep. And I would wake up tired and sore with a headache.  I could literally see my thoughts racing in my mind about things I had to do the next day, I got to the point I was only sleeping 2-3 hours a night, my neurologist prescribed me lorazepam & it helps. I fall asleep faster; however, I still wake up before the alarm but I'm well rested."
