Unfortunately, there is no successful method - without the assistance of a mechanical or electrical bodies. There are many supposed methods - banging one's head on the pillow, thinking about the time - even knowing the time to wake up - but these all rely on the principle of light sleep. If you are "dead" to the world or in deep sleep, then it won't make any difference. You will sleep through an alarm clock, an earthquake and even your mother shaking you.If you've had alcohol, then forget it.
The best way is to have enough sleep the night before to ensure you don't need a nap.
