I love, love, LOVE Spark energy drinks! After doing the 24-day challenge, I didn't stick with many of Advocare's products, but Spark is one thing I cannot live without. With so many flavors, there is bound to be one that works for you! My favorite by far is the Mango Strawberry. Followed by Watermelon (which is funny, because I normally hate Watermelon-flavored anything!) On the other hand, Pink Lemonade had a strange fishy flavor, in my opinion.
I am not a caffeine drinker normally, but Spark gives me just a little boost in my energy to keep me going throughout the day, without any sort of crash afterwards. As a bonus, all of the B12's makes you pee neon colors!
