text: i have a close friend who is a meth user (now in recovery) his behavior was similar to a schizophrenic. one day he was depressed, angry and over reactive, the next outgoing, cheerful and energetic. Many times he told me things and later seemed to not remember that he had told me or not remeber things we had done together. he would make commitment or appointments and the next day would have no reccolection of them. he would go through violent stages with almost superman like strength puting holes in walls and fighting with ppl 3 times his size and holding his own. i grew up with this guy and he never exhibited any of these quality or actions before his drug use. his recovery has been long and painful
