I thought it was a waste of time.... did nothing for me at the level of depression set from my PTSD. I say that, because depression that comes with PTSD is not what shrinks seem to so freely label as "major depressive disorder" but instead it is a chemical depression as a symptom of PTSD itself. PTSD feeds from stress, negative emotion, etc... fix those core issues, no more depression because the chemical intolerance is no longer constantly present.
