depression
"I read the experiences of people on Provigil before I tried it and as I was in the midst of a very deep depression and has tried so many other anti-depressants. I was suicidal and desperate for help.  As most other people found, it is a miracle!  I cannot believe that I feel this good.  I am back to my old positive self.  I am taking 200 mgm in the morning.  The last medicine that worked was Adderall which worked initially but wore off after a year.  I still had the rapid heart beat, but the depression continued.  Thank you to everyone who posted their positive feedback as it gave me hope that the medicine might work. This is an off label use, but it sure works for me!"
