Tammy Applegate dreams of sleep – when she dreams, that is. Most nights, she can’t sleep soundly; pain rousts her four or five times. She turns over, repositions the pillow under one shoulder – the only position that offers some relief – and waits for slumber to overpower her discomfort. “Sometimes it takes me so long to get comfortable that I stay awake anywhere from 30 minutes to a couple of hours,” says the Fort Worth, Tex., mother of four, who has mixed connective tissue disease and requires sleep treatments to resolve her issues with pain and sleep.
She’s got plenty of company. Insomnia – broadly defined as having trouble falling or staying sleep – affects anywhere from 10 to 40 percent of American adults, at least intermittently, according to population studies. It’s estimated that some 10 to 15 percent have long-term sleep problems (lasting more than a month).
