I absolutely love these! I can’t have energy drinks because they make my chest hurt and my heart feels like it’s going to stop, but with these I feel awake and alert, but not jittery. I also always hate grape “flavored” anything, except these. I love the grape ones so much! They’re sweet and taste so good!! My only criticism is that the paper wrapper under the cap is sometimes hard to get off, and you have to drink over the paper which feels weird, and makes it hard to open if I’m running late and want to drink this in the car. But other than that these are the best!!!
