Sleeping soundly should come easy after a day at school.
But, for many of us, nighttime slumber is disrupted by thoughts of our "to-do" list, worries about our studies or workload, or interruptions from roommates, etc. One-third of all American adults experience an occasional or persistent sleep disturbance known as insomnia. According to modest estimates, at least 20-30 million Americans suffer from insomnia.
