Have pretty regular sleeping hours. Keep the sleeping place dark (curtains). Dont go to bed hungry. Look out for coffee, also bad for anxeity. Carbohydrates can work as a sleeping pill, have for instance half a banana with milk, or some bread with honey or something like that when you want to sleep. It can also work if you wake up and want to go to sleep again (one half ripe banana, try it). Cammomille tea does also help you feel drowsy imo.
Also look out for alcohol, a hangover can make you uneasy, making it hard to sleep.
