The contrasedative is given to Mildred by two "handymen" who arrived to revive her from her suicide attempt. Montag is worried, but the men assure him that these things happen nine or ten times a night and not to worry. On their way out the men say that they have given her a contrasedative and that she will wake up hungry. A contrasedative has the opposite effect of a sedative- this will revive someone and give them energy, whereas a sedative will put a person to sleepw. Mildred wakes up with color in her cheeks and no recollection of her suicide attempt.
