I didn't think i'd like it at first. I ordered the free samples which were lackluster apart from the black cherry flavor, decided i would order to try it out. Had some of Clyde's black cherry flavor to stay awake after my overnight job, and get some work done around the house during the morning. Got me thru the rest of the day and was delicious as well. after a couple of days i felt like i had more energy, which i am sure is because of the vitamins. It is a way healthier choice then a monster energy drink every night. Not only do i look forward to drinking this during my break to stay awake thru the rest of the morning, i also enjoy the taste.
