Sonnet 118 by William Shakespeare
Like as to make our appetites more keen
With eager compounds we our palate urge;
As to prevent our maladies unseen
We sicken to shun sickness when we purge; 4
Even so, being full of your ne’er-cloying sweetness,
To bitter sauces did I frame my feeding;
And, sick of welfare, found a kind of meetness
To be diseased ere that there was true needing. 8
Thus policy in love, t’ anticipate
The ills that were not, grew to faults assured,
And brought to medicine a healthful state
Which, rank of goodness, would by ill be cured. 12
But thence I learn, and find the lesson true:
Drugs poison him that so fell sick of you.
