The UPI reports that “insomnia is reported by 54 percent of the 2 million U.S. men and women who served in various combat efforts since Sept., 11, 2001, researchers say.”

“Dr. Adam Bramoweth of the Department of Veterans Affairs Pittsburgh Healthcare System and Dr. Anne Germain of the University of Pittsburgh School of Medicine said those in U.S. military combat operations have more than double the insomnia rate than the 22 percent of civilian adults.”
