Sirach 31:19-21

New Revised Standard Version Updated Edition

¹⁹ How ample a little is for the well-disciplined!
    They do not breathe heavily when in bed.
²⁰ Healthy sleep depends on moderate eating;
    they rise early and feel fit.
The distress of sleeplessness and of nausea
    and colic are with the glutton.^(A)
21 If you are overstuffed with food,
    get up to vomit, and you will have relief.
