Almost everyone goes through bouts of sleeplessness from time to time. It happens to the average person about once a year. That's the cost of being human and having the capacity to worry about the future and chew over the past.
Chronic insomnia, however, is marked by difficulty falling asleep or staying asleep, or waking up too early. If it takes you thirty minutes or more to fall asleep, or you're awake for thirty minutes or more during the night at least three times a week for a month or more you're officially suffering from insomnia.
