Alright, let's knock this shit out of the ballpark fellow nazscientists.

First off, when you drink any energy drink marketed in the 2000's Energy Drink Craze Wave^tm, it reacts in a very special way, vastly different across cultures and species.

• In kids born on/after January 1^st of 2000 there is a mutation which has created a third tube beside their eaty tube and their breathy tube. This tube is solely used for the consumption of energy drinks. source

The energy goes straight to the energy center of their brain where hyperactivity and chaos ensue. The effects of drinking two 5 hours would be like driving a military truck with a nuke through an orphanage and their brain would liquefy. Luckily 5 hour tastes like shit so kids don't drink it.

• In 90's kids doctors can't remember how this would affect them. source

Effects include

..........................................................................................................................

• In millenials the drinking of 5 hours includes not opening the bottle, taking pictures for instagram, selling the 5 hour for $12.99 on eBay, and bragging/complaining that they didn't drink it. source

The effects of drinking two 5 hours energies would only be enough to counteract the excessive weed consumption

• For older people consuming energy drinks is "just like the old days!" and "what?" source

Scientist agrees that if an elderly person consumed two 5 hours, their heart would be put under arrest for leaving the old folk's home and ruining my childhood. Flashbacks would ensue; probably not real, but to be safe, let's take grandpa's Luger away.

• For faggot OP's consuming energy is their only motivation to rake dank karma. source

OP can bet his sweet ass drinking two 5 hours is going to give him double energy, but he's going to crash twice as fast because OP has no other hobbies and doesn't know how to party.

The only viable option is to continuously drink 5 hour energies until the virulent and unstable sphere that is OP's ego collapses in on itself, and they slowly realize the "life" they've experienced is nothing more than a carefully constructed facade to get you to drink more 5 hour energy.

Now comes in invisible flavor you big, stupid idiot!
