Insomnia can be a response to major life changes. It’s common to have insomnia after coming home from deployment. Insomnia is when you have a hard time falling or staying asleep, or you wake up too early. It can happen for short periods and then go away. But for some people, insomnia becomes an ongoing problem that causes issues at work and with relationships, mood and concentration, and is associated with many health issues. However, insomnia can be treated effectively by changing your behaviors to help you get more sleep and feel rested.
