September 2022 Update (Season 7)
First of you have have to drink 5 different energy drinks. Not 5 of the same brand.
Now thats out the way, this was a glitched trophy for alot of people. I had drank maybe 100 energy drinks before the recent update and couldn't get this trophy.
After this update I drank 5 different energy drinks again and it unlocked no problem. Although some people will still run into some issues with the glitch. It is fixed for the majority of gamers right now.
If you've been trying to get this and failing, then there is no better time to jump into the game and unlock this.
If you need more energy drinks log in everyday at 9pm GMT. This will net you experience for energy drinks unlocks. Also on some special days they will give you energy drinks for logging in.
Happy hunting.
