depression
"This turned me from a deep, suicidal depression into a happy, productive person in 2 days. I am also able to sleep without any sleep medicines (first time in years). My problem is that my insurance refuses to pay for it because using Provigil for depression/bipolar is off-label, and it is so expensive that I'm just starting to wean myself off of it, sadly.  There is another drug, Nuvigil that is supposed to be even better, and is currently being tested (very positive results so far) for FDA approval in the use of it for depression and bipolar.  It's been a long road for me, so I can only pray that the FDA moves quickly on this."
