We speak with a lot of insomnia sufferers. Those that truly inspire us are the ones who have chronic insomnia, yet accept it as part of who they are. Insomnia can be truly debilitating, yet these people still remain productive and surprisingly positive.
We were reminded of these people when we came across this post about mimicking the benefits of sleep as a way of relieving your insomnia. The author of that post has a financial stake in the advice she gives (she has published a book and runs classes) - however, what she says makes a lot of sense and is very interesting.
In short, you should use the time you're awake to meditate, slow down your mind and connect with yourself. It all sounds very spiritual, but it could be worth a try - we've heard from a lot of people who have told us that acceptance and meditation have helped them cope with their insomnia.
It may not be a cure, but it could well help.
