Distention of the stomach should be prevented, as the diaphragm is thus pushed up against the lungs, and the gas is accumulated in the cavity. All these conditions often occur in our waking moods, but then our judgment tells us how to relieve them speedily; whereas, in sleep, the load accumulates. All indigestible substances, therefore, should be avoided, as nuts, cucumbers, shell-fish, &c.
