How long does a red bull last?!

Ok, lets see, you'll be at the NYC Sr. Regis in a separate room from your parents with your best friend and one raging red bull between the two of you. 14 y/o and 145 lbs. I suppose you could sip off that red bull for hours if you really want to make it last. But is that what you really want? I say you chug it all at once and leave your buddy sane, sober and in control in case you freak out.

It depends on how tired you are, if you're like me and are pulling off constant allnighters then it's only going to last about 2 hours, if you drink more than one at the same time(not recommended) it might last 3 to 5 hours. if you're casually drinking it and you're not that tired, like to get a little boost or something like that then it's gonna last a long time and you might not even crash. Try and take into account what you're doing how boring it is and how tired you are. If you feel your heart racing then you've had way to much. Sounds like you're just partying and having fun, it'll last a few hours but since you're probably having a lot of fun then you're not gonna crash no matter how tired you are, when you crash the day after go to bed and don't let anybody wake you up.

I drink a 4 pack of redbull daily. Constant allnighters aren't easy

depends if you are already tired than you'll have to drink a lot to have a long lasting effect. But yes you will have a huge crash feeling after. the longer you're energized and more you drink the bigger the crash.

personal experience
