Conditioning your body to a physical stimulus

Sounds crazy, but due to our biological instincts are strongly conditioned to physical stimuli. So every night, when you're ready to fall in snoring, give a concrete physical sign - something you would not normally do. A good example is to pick your nose as in the picture, as a gesture of not ta to smell a peidinho. Keep repeating this motion until you sleep. In two or three weeks, your body will learn to recognize this signal as the beginning of sleep time. You only have to repeat this action when you are having problems off to convince your body that it is sleepy.
