Refresh your day with Day 4 of the 7-Day Infused Water Challenge: Lemon Cucumber Water. A hydrating, detoxifying drink for ultimate wellness. I can hardly believe it's already Day 4 of my 7-Day Infused Water Challenge! And so far, it's been an amazing journey. I'm honestly excited every day to discover how each new fruit and vegetable combination will taste. If water always tasted this good, I think I'd be sipping on it every minute of the day, who knew hydration could be this refreshing and fun?
