18 If you are seated among many persons, do not help yourself before they do. 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. 22 Listen to me, my child, and do not disregard me, and in the end you will appreciate my words. In everything you do be moderate, and no sickness will overtake you.

To me, the star called by the mathematicians Acephalus (headless), which is numbered before the wandering star, his head resting on his breast, seems to be a type of the gluttonous, the voluptuous, and those that are prone to drunkenness. For in such the faculty of reasoning is not situated in the head, but among the intestinal appetites, enslaved to lust and anger. For just as Elpenor broke his neck through intoxication, so the brain, dizzied by drunkenness, falls down from above, with a great fall to the liver and the heart, that is, to voluptuousness and anger: as the sons of the poets say Hephæstus was hurled by Zeus from heaven to earth. The trouble of sleeplessness, and bile, and cholic, are with an insatiable man, it is said.
