Millions of people often have trouble getting a good night's sleep. So, what can be done? The St Francis Hospitals and Medical Centres of Indiana says most sleep problems can be remedied with lifestyle changes. If you have insomnia, the hospital advises:

• Avoid caffeine or tobacco six hours before bedtime
• don't nap
• don't use your bedroom as an office or to watch TV
• and set aside time earlier in the day to worry about things that are bothering you, so you don't lie awake thinking about them. - (HealthScout)
