It usually takes several uses of Coricidin on high doses (ranging from 8 - 56 is the most i've seen taken at once, 56 was by myself and yes, I did OD.)
Coriheads usually believe that Coricidin provides a form of "enlightenment" or "a religious experiance." Coriheads often try to act very literal, which can make them come off as a creep or not understandable.
Coriheads are advised to quit use of the drug compleatly.
