The feeling that comes after the sugar rush. After the hyperness is gone. The sugar CRASH. 
You start to feel hot, and possibly shaky, like you have a fever.
You may also get an upset stomach.

Get the Bieber Fevermug. a lot like cabin fever, except that it is in a car. it is that point on a long road trip where you are about 8 red bulls down and have been driving for about 5 hours straight. symptoms include: eating cold chicken nuggets from 7 hours ago, you start singing the most ridiculous songs as loud as you can, you start talking to yourself, having conversations with siri on your iphone, and other random things.
random guy passing you: "man that guy is really going at it on them air drums."
his wife: " he must have carbon fever."

Jorge: I cant take this anymore, i got Barrens fever. i just want to kill myself
