Insomnia is a common problem. About one-third of all adults complain of insomnia each year, and approximately one in five report that it is a serious problem. The most common complaints are transient insomnia lasting a few days to a few weeks, often associated with a stressor, a major change in one’s life, or a major change in one’s daily routine.
