Sleepless is both a personal account of the author's inability to sleep and a poetic survey of a range of artists and others who have suffered from chronic insomnia-a book for everyone who has found sleep elusive.I lost sleep. I retraced my steps but sleep wasn't following me. It had broken free and I was wandering through the night without it.The world is divided into those who can sleep and those who can't.What is it like to live with chronic insomnia? For Marie Darrieussecq, not sleeping began after the birth of her first child and continues more than twenty years later. She wonders if it is connected to her hypervigilance, to her fear of her children dying. Once they leave home, will she finally be able to sleep again?Or, she wonders, will writing this book help her to sleep again?In Sleepless, she recounts her own experiences alongside those of fellow insomniacs, mostly writers-'as if writing were not sleeping'-Ovid, Marcel Proust, Virginia Woolf, Marguerite Duras, Franz Kafka, Georges Perec and others (some of whom claim a connection between insomnia and creativity). With her inimitable humour, she describes her dealings with a somnologist and her attempts to find a remedy-she tries all manner of sleeping pills, cannabis, alcohol, bedtime rituals, acupuncture, yoga, hypnosis, psychoanalysis, a gravity blanket and a range of sleep-aid devices.Darrieussecq considers bedrooms, beds, clinophilia ('the tendency to remain in a prone position without sleeping for prolonged periods of time'), her need to be alone in bed, those without beds, the homeless, refugees, trauma and capitalism's role in sleeplessness, our constant wakefulness online, the forest as a hypnogogic zone, and how our relationship with animals is connected to our sleep, or lack of it.Sleep or no sleep- it matters to all of us. Sleepless will awaken you to the otherness of our world, to erased presences, ghosts, endangered species. Insomnia feeds off this bewildering feeling- there is something else.
