multiple sclerosis
"Provigil gets 9 out of 10 ONLY because of the extreme headache I get when I don't take it A--with lots of water (and a little food in my stomach) and B--before 10am.  I've had Multiple Sclerosis for 7 years now and have been on Provigil for the last few years to fight the fatigue and lack of focus associated with MS.  And it even has the "bonus" side effect of making me HAPPY again.  Most people who have MS know that depression is also a silent struggle that never gets acknowledged.  Provigil makes me physically less "worn out", makes me mentally alert and makes me emotionally just in a better mood. I guess I can't say enough good things about it.  If you can tolerate the headache you might get, this medicine is WORTH IT."
