Undereating in the evening is especially important for many nervous people and is often the source of wakefulness. It is the cause of insomnia, not so much at the beginning of the night, as a rule, as in the early morning. Many a person who wakes at four or five and cannot go to sleep again is hungry. There is a sense of gone-ness in the stomach region in these cases, which the patients are prone to attribute to their nerves in general, or some of them who have had unfortunate suggestions from their physicians may talk of their abdominal brain; but it is surprising how often their feelings are due simply to emptiness. Any thin person particularly who has his last meal before seven and does not go to bed until after eleven should always take something to eat before retiring. A glass of milk or a cup of cocoa and some crackers or a piece of simple cake may be sufficient, but it is important to eat enough. Animals and men naturally get sleepy after eating and do not sleep well if their {161} stomachs are empty. Children are the typical examples. We are all only children of a larger growth in this regard. When the last meal is taken before seven and people do not go to bed until nearly twelve, as is frequently the case in large cities, the custom of having something to eat just before bed is excellent for sleep. I have known the establishment of this habit to afford marked relief in cases of insomnia that had extended over years. The people in my experience who sleep the worst are those who, having taken a little cambric tea and some toast and preserves with perhaps a piece of cake for supper, think that this virtuous self-control in eating ought to assure them good rest. It has just the opposite effect. Disturbed sleep, full of dreams and waking moments, is oftener due to insufficient eating than to overeating. The people whom I know who sleep the best and from whom there are no complaints of insomnia, are those who, having eaten so heartily at dinner that they get to the theater a little late, attend the Follies or some late show for a while and then go round to one of the Broadway restaurants and chase a Welsh rarebit or some lobster a la Newburg, with a biscuit Tortoni or a Pêche Melba down {162} to their stomachs and then go home to sleep the sleep of the just.
