'I am fairly confident that most of us, at some time in our lives, have experienced trouble sleeping.
For some of us sleeplessness can come during times of transition…like when we move into a new home or travel. This type of disturbance in our sleep pattern will usually only last for a couple of nights.
Then there’s the type of insomnia that carries on for a couple to three weeks and is usually caused by anxiety or stress.
On the other hand, it’s chronic insomnia — or poor quality of sleep occurring three or more nights a week for months at a time – which can be a real cause for concern and generally requires an investigation to uncover the root cause of the problem.'
