Bests & Worsts Reviews from Amazon

I didn't realize they were caffeinated. Since one bottle is more than one serving, and I am using these to help keep pushing fluids instead of just water, I have to be careful. I drank two one evening before I realized they were caffeinated and had a heck of a time getting to bed that night. I don't drink soda or coffee after lunch, though, so I could be more sensitive than others. Just a heads up!
