I used to have racing thoughts, it was constant fighting with myself and sometimes with other two voices. Sometimes it was just two voices with my own voice. Then other times, another was added it could be the voice of a boyfriend etc. All different trains of thought. Now I wonder,how fast was my brain working to have so much crap running. It took me forever to go to sleep too, because I just couldn't have my mind blank at all. When I tried I was constantly talking to myself "be blank"... I don't think that's how it works lol After using topamax they went away, my train of though/cognition became noticeably slow too. When I stopped the medicine because I was so blank I couldn't even retrieve my memories, nothing went back to normal. I only have one consciousness voice, no more super speeding obsessive thoughts. Things slowed down, I'm not as fast thinking as before. I don't know how or why it became permanent. I still can't believe it happened... But only God knows, probably it was a good thing..
