i only worked on xanax and later vics or oxy i could work harder and longer and no one noticed unless they were users themselvs like id get aggressive and my peuples were non-existant. they permoted me like 10 times i was always moving and after work nodding off, morphine mixed with xanax made me go nuts after a while. i quit useing and quit my job after 7 years of useing on the job now i dont do shit and it sucks like im healthy but i hate talking to people now
