ok, so i have tried RockstaR energy drink because i heard it’s one of the best energy drinks that taste good and gives you energy; however, I don’t feel energized at all! i have tried 2 types of RockstaR, original, and the ZERO CARB(this one supposably was the best at energizing and has more caffeine) i sometimes work late so I try out the energy drink but end up feeling sleepy even after drinking RockstaR. and yes i drink the energy drink when and before i feel sleepy or out of energy. anyone know whats going on here? and what energy drink “really” works?
