What is Insomnia?
Insomnia is defined as difficulty getting to sleep or staying asleep for long enough to feel refreshed the next morning.
Most of us will have experienced this at certain times in our lives and will know just how frustrating it can be. A disrupted night can leave you feeling drained and irritable and so anyone with insomnia will experience these feelings on a regular basis.
Conservative estimates show that 10% - 30% of adults live with chronic insomnia and other studies show that this figure is closer to 50% to 60% (http://sleepfoundation.org)
