What is the best treatment option for severe chronic insomnia?

Begin with eval: The best treatment would begin with an evaluation -- probably with both a psychiatrist and sleep medicine specialist. Some physicians have both these qualifications, and you need careful consideration in both realms. If there are additional symptoms like movement & speaking problems you may need a neurologist in your team as well. Then, helpful treatment suggestions can be made.

Depends: As previously answered start w/ medical evaluation. Otc, herbal, and nonprescription remedies are not entirely benign and most have warnings abotu drug interactions, and more than short term use. Cognitive-behavioral therapy with relaxation traingin and sleep hygiene has been found to be more effective than meds: http://cpancf.Com/articles_files/psychotherapeuticotcherbalinsomniatreatments.Asp.
