How to treat insomnia
Find the cause or source of your insomnia.
Try to find what is preventing you from falling asleep and, if possible, eliminate it. You may need to fix other problems and issues first in order to treat your insomnia.
For example : If anxiety or depression are keeping you awake at night, find what is making you feel anxious or depressed and try to manage that. This might involve speaking with your doctor and taking medication for anxiety or depression.
