Narcolepsy
"After trying almost every sleeping medicine approved in the US, nothing has worked better for my narcolepsy.  I haven&#039;t had any negative side effects, and I have been treated with Xyrem for more than 2 years.  Little by little over the last 24 months I have noticed that my memory has improved, my reflexes are faster, and I am able to work 40 hours a week on my feet, without being abnormally tired.  It has truly given me a life I would have never experienced. I was &quot;sleeping&quot; my life away 14 hours at a time."
