Think of all the syptoms of overdrinking....Not being able to constuct a sentence, stand up, think straight, excessive urination from the caffeine, the start of insanity..... Revision is exactly like being drunk. Henceforth the term....'Revision Drunk'
When you're on your fourteenth hour in the library revising and the smallest of tasks like stringing a sentence together becomes impossible when you're brain has turned into mush from the caffeine and sugar overload! And you can't even walk in a straight line when you stand up due to sitting down for so long.. revision drunk!
