Moutain Dew-The best soda ever. My friends and I drink this all the time. I'm so used to it only 18 cans can get me hyped up now. Unless its 3 a.m. and you are doing nothing but studying or gaming then it works.
Vault-Second best soda ever.
Red Bull-Meh, not all the great.
Monster-I have only had the green kind before and i really liked it.
But with energy drinks some just take an aquired taste. But yeah, in my personnal use with them they don't really do anything bad to you unless you drink WAY to many and it can actually make your heart explode. But yeah, just drink an energy drink and have some water with it, because if you also drink too much you can get de-hydrated and you get all sick and you won't be able to do anything then.
