i started taking it several years ago (100mg/day) for loss of focus with depression. the first thing i told my doc was that my pps pain was diminished, no one had any idea why.
at one point, wasn't taking it, that constant pain came back.
then i remembered and started again, and wham, the pain is alleviated.
no one knows why; it's not in the literature anywhere.
so glad to hear that someone else has had this experience.
