It is here that the cause of sleeplessness and its remedy we believe largely lie, for it is within the power of all to put themselves into the control, more or less complete, of their sub-conscious self and develop the power of the sub-conscious self until it becomes a real potency. To take an example, how constantly does it happen that after wrestling with some mental difficulty, or trying to remember some name which one knows well, one by instinct dismisses the subject, to find in a few minutes that the difficulty is solved, or the name recollected. That is probably the work of the sub-conscious part of the brain. In the same way many people can wake themselves at any hour they wish, by telling their sub-conscious brain (this is what it comes to) to call them. They go to sleep, having ordered their sub-conscious self to call them, and at the appointed hour, it may be long before light, something inside them, which apparently knows the time, wakes the rest of the sleeping brain and body. And with a little training and practice the power of developing and using the sub-conscious brain increases very quickly. We believe that many early wakers could sleep comfortably on, by saying that they would _not_ awake till a certain hour. One does not need violence or internal shouting, as it were, to communicate effectually with this sub-conscious self; a quiet determination of thought for a few moments before going to sleep does the work effectually. This also is invaluable to many who have found that going to sleep when getting into bed was difficult. One has to take it for granted that one is going to sleep, and cease to think about it, emptying the brain of conscious thought as far as may be. You cannot go to sleep in a rage, until the rage has given place to exhaustion. To sum up, then, both for those who find it difficult to go to sleep, and for those who wake early, the following hints are recommended:-- (i.) Do not load your brain with interesting stuff, just before going to bed. This will both prevent your going to sleep, and will also tend to wake you up. Try reading a stupid book for a few minutes after getting into bed. (ii.) Have as much air as possible in the room, and wear the minimum of bed-clothing that keeps you warm. But have an extra rug over the feet, which you can easily draw over you towards morning, when both the night is coldest, and your vitality lowest. (iii.) If you still lie awake, try the effect of some monotonous exercise, like counting sheep going through a gap, marking out a tennis-court, or repeating some short and familiar form of words. (iv.) If you suspect even slight indigestion, take a little bi-carbonate of soda or of potash. (v.) Tell yourself quite quietly that you _are_ going to sleep, but do not rouse yourself to see how you are getting on. (vi.) Eat or drink something easily digestible, rice, biscuits, or hot cocoa.
