Narcolepsy
"I&#039;m surprised by the majority of people&#039;s reactions to Nuvigil (though, it&#039;s the only medication I&#039;ve tried so far). Before starting up with the medication I was exhausted to the point of feeling sick most of the time. After starting the medication it&#039;s like night and day, I typically feel great. Some days are better than others, and I never feel 100%, but it&#039;s the best I&#039;ve felt in years and it hasn&#039;t fluctuated in two months I&#039;ve been taking it."
