Insomnia can vary enormously in its intensity and its effects, ranging from a minor irritation to a life-wrecking affliction. It may be a temporary problem caused by undue stress or the product of serious emotional difficulties. Either way it is amenable to treatment however and the benefits of sorting it out are enormous.
I have successfully helped people at either extreme to resolve their difficulties, turn down the mental chatter and enjoy the benefits of healthy restful sleep. If you have suffered from even minor insomnia then the benefits of sleeping well can be truly life-changing. You'll have more energy and feel much better about almost everything in your life.
