What is insomnia?

- Your sleep history. Be prepared to describe your insomnia with details such as how long it has been going on, what you think could be contributing to it, and what your sleep is like, such as whether you can barely get to sleep at all or if you wake up too early.
- Physical exam. The doctor will look for any physical reasons that could be causing sleep problems.
- Sleep study. You may need to sleep overnight in a sleep lab where researchers monitor your sleep. To learn more about a sleep study click here.
