Nuvigil
"First day on Nuvigil prescribed by a "second opinion" sleep doctor.  My first sleep doctor kept discounting my complaints of constant sleepiness even after having the CPAP machine for over a year. He had never even talked about any medications for excessive sleepiness.   But, my "second opinion" sleep doctor did pay attention.  I can't thank him enough.  My first day on Nuvigil has been like a sunrise.  This is the first day in at least 6 years that I didn't fall asleep.  No headaches, jitters, nausea. Started to feel the "wakefulness" easing off after about 6 hours.  I agree about the cost, it's outrageous at over $10/day.  I also take medicines for Atrial-fib, so Nuvigil is one of the few I can take."
