mmm, gotta love me them NAPLAN tests. Oh the misery I go through, knowing that there's no NAPLAN tests in Uni. Such heartbreak, such heartthrob, makes me so sad.
I hear the best way to get rid of a headache is to cause pain somewhere else on your body. (Not really, I wouldn't recommend it). If you have panadol, those work. Otherwise a glass of water and lay down and sleep it off.
