For as a surfeit of the sweetest things
The deepest loathing to the stomach brings;
As the heresies that men do leave
Are hated most of those they did deceive,
So thou, my surfeit and my heresy,
Of all be hated, but the most of me.

– William Shakespeare

A Midsummer Night’s Dream, Act 2, Scene 2. Lysander tells why his love for Hermia has turned into such intense hatred. He uses two metaphors in the course of his explanation. One compares his change of heart to an excess of dessert: eating so much of a good thing that it makes one sick to the stomach. The other likens it to men who abandon a belief becoming its strongest critics when it is shown to be false.
