http://www.mentalhealthamerica.net/melatoninMood disturbances, paranoia, psychosis, etc. It fits. For nearly a decade I've been getting those symptoms, and for nearly a decade I've been taking melatonin. It's a rather unique altering of ones consciousness, but I can't warn against it more. The paranoia alone has caused me to get into too many dangerous situations.
Has anyone else been through this?
