Sirach 31:19-21

New Revised Standard Version, Anglicised Catholic Edition

¹⁹ How ample a little is for a well-disciplined person!
    He does not breathe heavily when in bed.
²⁰ Healthy sleep depends on moderate eating;
    he rises early, and feels fit.
The distress of sleeplessness and of nausea
    and colic are with the glutton.
²¹ If you are overstuffed with food,
    get up to vomit, and you will have relief.
