Most people suffer from insomnia at some point in their lives. In fact, more than half of us will have trouble sleeping in the course of any given year.

For some, the mere thought of not being able to get a good nights sleep gives them insomnia. For others, sleeplessness is a debilitating symptom of wider conditions like depression, stress, anxiety, chronic pain or the menopause. As any new mum with a hungry or colicky baby will tell you, lack of a good nights sleep makes you crabby, forgetful and miserable. Simple things can seem difficult as both brain and body become overwhelmed with exhaustion.
