Narcolepsy
"After years of misery; then numerous tests by neurologists and sleep studies I was finally diagnosed with severe sleep apnea and a form of narcolepsy in 2005.  I was prescribed Provigil, 200 mg twice a day and given the okay to take another 1/2 tab if necessary.  It was a Godsend and changed my life for the better.  However, now Doctor wants me to &quot;try&quot; Nuvigil and gave me samples and prescription.  It DOES NOT WORK for me but insurance company is demanding I stay on Nuvigil. Provigil will cost $1000 pr/mo! "
