Do those power drinks taste like a very very strong coffee? Do you feel extra energy after drinking it?
Are the flavored vitamin water drinks have cherry or lemon or whatever taste in them?
Is it worth the money?

(I put this in Seniors catagory because I wanted to hear if it gave my age group any extra energy. I am 65).

If there is an energy boost, it can be short-lived. Some of them contain high levels of caffeine and sugar, but some also have herbs. Attached is some information that is worth reading, as there have been reports of people becoming sick (but likely from taking too much.)
