Wisdom of Ben Sira 31:19-21

New Catholic Bible

¹⁹ A small portion is sufficient for someone of good upbringing;
    when he lies down, he experiences no discomfort.
²⁰ Moderate eating ensures sound sleep;
    such a man rises early and feels refreshed.
However, sleeplessness, nausea, and colic
    are the lot of the glutton.
²¹ If perchance you have eaten too much,
    get up and empty your stomach, and you will find relief.
