I recently switched to a buckwheat pillow as per my acupuncturist's advice, and I have to say I was very surprised how much better I sleep. A car accident left me with chronic neck pain and insomnia, and I was beginning to think I would never be comfortable again. Crazy how such a small change can make such a large improvement :))
