I liked them (my DD didn't so I snagged hers), I like that they weren't too sweet.
However after I drank 2 at 3pm and when I tried to go to sleep at 10pm, it was so not happening. At 2am I gave up and took a MotrinPM. I felt like a drug addict, I needed downers to get me off the uppers. I'm not used to consuming lots of caffeine and it didn't feel like I was since it was just fruity.
Lesson learned!
