It's been said over and over again for a reason-because its true! Most people don't drink nearly enough (and even if you think you're drinking enough, you probably aren't, especially if you're trying to gain health and lose unhealthy habits). Bring a water bottle with you wherever you go and invest in a simple filter for your home. Water is especially important when adjusting to a new way of eating, as it will help curb any cravings you may experience.
