I have taken dopamax as I call it too. I became forgetful and plain dumb as a rock, not being able to remember words to express myself and forgetting things I was supposed to do. It helped me lose some weight but besides this it was a frightening experience. I thought I was losing my mind which was already screwed up from mental illness. My memory was extremely impaired, and it really did not help me with my mental disorder. I stopped it and although I am still dumb as a rock, I returned to being semi-coherent.
