Narcolepsy
"I am 30.  I have narcolepsy, fibromyalgia and severe rheumatoid arthritis that is also in my organs. I take 20mg every 4 hours up to 4 times a day.  It takes 30min to kick in, and wears off in 2 hours.  Without it, I felt like I had to curl up on ground wherever I was at or I wouldn&#039;t &quot;make it.&quot;  With the medicine, I feel totally exhausted, but it takes the edge off the urgency to lay down.  I have been on it for 2 1/2 years.  Docs wan&#039;t me off it (since it&#039;s a stimulant) and wants me on Nuvigil.  I took one pill 150mg with Ritalin, seemed to help but it&#039;s been one day (tapering off Ritalin).  Ued to fall asleep driving every day working full time.  Now  work part time and take methylphenidate and don&#039;t fall asleep driving (that I know of)."
