Energy Drink Collection

Hey people,
a month ago I started my energy drink collection and I got em to 30 yesterday and thought it's time to share.
I'm not actually a big fan of energy drinks, because they have mostly negative effect and most of them don't even help me stay "concentrated" and "energized" for more then an hour in the night. Good thing WoW was interesting enough on its own ;D
So what's your opinion on energy drinks? What's your favorite?

Changing name ;x

I guess we are changing the name of the group from LFGFS to pH7
You can say which one you like more

also Cataclysm was great ... stopped playing for some time. I guess school (by school I mean girls) is more important
