anxiety
"I was having severe menstrual cramps, and took this.  Though it did nothing for my pain, the effect it had on my mood was amazing.  I have suffered with severe mood issues most of my adult life, and none of the many antidepressants I have tried did anything to help.  Within an hour of taking it, I felt normal for the first time in 15 years.  I talked to my physician, and she agreed to prescribe it off label to treat my mood disorder. I have been taking the same dose of 50 mg, three times a day for the last three years, and I am doing great."
