First think about your body. Exercising regularly will help you to fall asleep more easily. You should try to drink less coffee and smoke less, too. These bad habits keep you awake. Don’t use devices with bright screens, for example, your mobile phone, before you go to sleep. They make your brain think that it is daytime, instead of night. Read a book and drink a cup of warm milk or herbal tea in the evening. Then you’ll feel ready for sleep.
