Just flip to go beyond caffeine and chamomile.

Filled with recipes for food and DIY health and beauty treatments, Wake/Sleep is two books in one: one half has advice and tips on staying alert and energetic, but turn the book over and discover the best ways to calm down, relax and fall asleep.

Caffeine features heavily on the Wake side but eucalyptus and citrus are fascinating and stimulating alternatives. Recipes span from the perfect bulletproof coffee-the added fat slows down the body's absorption of the caffeine for a smoother buzz-to Matcha Mint Gummies and Chocolate Stout Chili. On the Sleep side, calm your body and mind with sweet potatoes, pumpkin and calcium and magnesium-rich foods, with recipes including Peppermint Tea Latte, Lemon-Lime Avo Mousse and Banana Pudding.

DIY Coffee Body Scrub will energise even the most reluctant morning person and, when it's time to wind down, a calming Yogurt Bath Soak will promote relaxation.
