Okay; point taken. With the amount of people who have cracked, I guess if you think you're in a similar position - or on your way there - then it'd make sense.
All I meant was; it takes a while to get into the rhythm of studying, and everytime you take a break, it just jolts that rhythm slightly. Going out every night and then, spending an afternoon off etc, that's all important to keep things in perspective, but I think taking a week off would knock off the focus too much.
Then again, all this is very subjective, as different people's minds are differently attuned to the ideas of study.
