Why are we doing this study?

Sleep problems are common among those with exposure to trauma and can contribute to other mental and physical problems. Medications and other treatments aimed at reducing PTSD have not been very effective for helping insomnia. Suvorexant is a drug approved by the FDA for treatment of insomnia but it has not been evaluated for treating insomnia related to trauma. We want to find out what effects (good and bad) suvorexant has trauma-related insomnia.
