What works for me is having a balanced life, eating healthily and doing a lot of sport - mens sana in corpore sano ;) - which gives me a lot of energy during the day too. Avoid anything exciting or stressing in the evening.

Watching movies or reading books make me feel more sober. Maybe you can try to lie on your bed. Close your eyes. Then start to use your mind to write a story. I always do that. And will have nice dreams in this way.

watch a boring movie

Daily meditation about 10 mins - 15 mins can help your mind feel relax and you could fall asleep easily
