yup all the time.. i kinda used to 'do something' and it destroyed my mind alot... i finally recovered from full blown retard status (i couldn't say anything without stuttering and couldn't think of easy words, i basicly couldn't even put together a sentence) it still effects me now... i'm no where near what i used to be, in brain power i mean...

it helps me concentrate on what i'm trying to concentrate on...

the only way i can really explain it is my thoughts are a candle... and sometimes a wind just comes by and blows it out and i don't have matches to light it up again.... but talking to myself is like taking out the candle and just putting in a light bulb... it still goes out now and then, but it lasts alot longer then that candle..
