The whole video I was like, what the fuck does this kid want from me?
Maybe he wanted to get drunk off energy... who knows...
Like Cake said, it doesn't really takes effect on me unless I drink like twenty of those and my stomach assplodes... my friends drink that shit for some reason.
My point of view is, it's either you get drunk a bit and go to sleep or you drink so much coffee so you won't be able to sleep for like the two next days...which is what I usually do.
