I only discovered that This Work's Deep Sleep Pillow Spray actually does works on a recent work trip to Liverpool. I was staying at the Crowne Plaza, and the hotel and This Works have teamed up to create a little tiny spray and roll on set that sits by the side of your bed. I've used it every night since.I'm not sure if this is just a placebo product, but I'm willing to take the risk. I don't actually suffer from bad nights sleep or insomnia, but recently I haven't been sleeping like I used to (when I was younger!). Now though, with a few little sprays of this gorgeous lavender, vetivert and wild chamomile concoction, I'm asleep quickly and deeply.This is a big 250ml limited edition bottle, available here at Feelunique.com (and in the sale for £27). The print on the box and bottle is gorgeous, very Marni-esque.
