What do you do for a loved one who suffers from nightmares after being in the military?

Encourage help: Encourage your loved one to seek care. If her or she has symptoms of post traumatic stress disorder they can seek assistance through a vet center or veterans affairs medical center. Ptsd related to deployments is usually complex ptsd which is very different from simple ptsd. It is usually beneficial to work with providers who understand the military and deployments.
