Interestingly, 85% of patients with unipolar depression report that they suffer from insomnia, even though bipolar patients tend to experience hypersomnia - excessive sleeping - during depressive episodes. Hypersomnia is also a characteristic of Seasonal Affective Disorder - along with decreased quality of sleep, which is also found in depressive patients, whether insomniac or hypersomniac. This poor-quality sleep can, in turn, lead to fibromyalgia, a painful, nondegenerative muscle disorder. All these patients can benefit from good "sleep hygiene" - a disciplined regularizing of sleep/wake hours. Depressed patients and those with fibromyalgia are also often treated with antidepressants such as amitriptyline and trazodone, which have sedating effects.
