The study by Edinger et al1 on cognitive-behavioral therapy (CBT) for insomnia clearly demonstrates the value of directly targeting sleep disturbances among patients with fibromyalgia (FM), and their impressive results support the emerging sleep medicine paradigm to treat “insomnia as a disorder.”2 The large treatment effects for many self-report measures prove that treating insomnia as if it were a comorbid condition is highly beneficial to FM patients.
