My 12 Hours as a Madman
by Sidney Katz
From the October 1, 1953 issue of Maclean's.
On the morning of Thursday, June 18, 1953, Sidney Katz swallowed a drug which, for twelve unforgettable hours, turned him into a madman. For twelve hours he inhabited a nightmare world in which he experienced the torments of hell and the ecstasies of heaven.
