Chamomile is often cited as a natural way to help people sleep. You can get it in the form of tea or use chamomile oil on your neck, feet, and hands to help relax the body. If using the tea method, it's best to put honey or lemon in it.
If you are not tired when you go to bed, then get up and watch TV or read a book. Take a warm shower or bath; this will help you to relax. Another helpful suggestion would be to arise earlier in the morning and make sure you do not take a nap during the day.
Warm milk, which contains triptophan and melatonin, can aid you in getting to sleep. Triptophan in turkey is well known for causing drowsiness. OTC melatonin, 1mg to 3mg, also works.
