narcolepsy
"I diagnosed myself after reading a pamphlet in the Doctors office the other day.  It was like reading the story of my life for the last couple of years.  She put me on Nuvigil and I'm currently on my second day of it.  I've noticed a lot more awakeness and anxiety.  Slight heart issues I think like racing from time to time and one severely sharp pain yesterday but otherwise I really feel much better.  Too bad it's too late to save my marriage but at least I will be able to build a new life where before there would have been no way to cope.  Wish me luck guys.  I've had no headaches or jaw issues either."
