Just to make it straightforward, i simply do not like redbull energy drinks at all. in my mind, it tastes like crap, kind of like coke without the sugars or something and the energy it gives feels extremely artificial. The energy just is too intense for a too short period of time, it just feels like you get a temporary high and you crash. In terms of physical energy, i guess it is okay, but it just does not last long for me. Mentally it is disastrous though, i always get severe headaches after the energy runs out, and it is just painful to me. I really prefer other drinks such as monster or amp.
