MACBETH: Canst thou not minister to a mind diseased,
Pluck from the memory a rooted sorrow,
Rase out the written troubles of the brain,
And with some sweet oblivious antidote
Cleanse the stuffed bosom of that perilous stuff
Which weighs upon the heart?
DOCTOR: Therein the patient must minister to himself.
-- William Shakespeare, Macbeth
