Stop insomnia by putting a few drops of
Lavender Essential Oil on your pillow, on your nightie, or directly on your temples. Or, you can put the oil in a diffuser in your bedroom. The lavender slows the activity of the nervous system, promotes relaxation, improves sleep quality, and reduces anxiety. (If you use a candle diffuser, be sure someone else is around to blow out the candle because you will be fast asleep.)
If your case is so severe that the lavender essential oil is not enough, you can take valerian in capsule form. Valerian Root will let your body and mind totally relax, without feeling stoned or drunk, and with no "drug hangover" the next morning.
Soaking in a warm bath a few hours before bedtime, and exercising during the day will help insomniacs. Going to bed at the same time and getting up at the same time each day will also help.
If you read in bed, use a book lamp or a table lamp next to you instead of an overhead lamp. This keeps the light on the book instead of you, which prevents melatonin from being secreted in the evening. Melatonin is responsible for causing sleep, and extra light at night interrupts the normal sleep cycle.
