The Mood Cure by Julia Ross

You know that moment where you feel like you snapped from a good mood into a bad one, and you can't figure out how it happened, much less how to make it better? Well, in her thirty years of experience, Julia Ross has gotten to the bottom of mood swings and has developed a four-step system to getting ahold of seemingly impossible-to-control emotions.

This tome is especially helpful if you're wary of therapy or drugs. While not a replacement for medical treatment, Ross has found that changing one's mood can be as simple as changing one's diet, adding key supplements, or improving one's sleep schedule. This book is a great reminder that given the right building blocks, the body can heal a myriad of ailments — amazing, right?
