I used to drink them all the time, and I think at first they did wake me up a little bit, but then after drinking so many, that effect soon wore off. Now I don't drink them because my heart started hurting and they really mess up your oral hygiene. Red Bull is the only one I can tolerate these days if I do happen to drink one, but the majority of them make me feel physically sick.
Any of you a fan of these drinks or despise them completely?
