So...
Get to the hospital and go in for my test. She sticks the needle in my arm and says 'oh your veins have disappeared, I tell her I'm feeling a bit dizzy. Next thing I know I'm coming round, lying down, nearly choking on my own vomit. Turns out I passed out and started having what looked like some sort of fit. Needless to say they decided to abandon the test. I now feel like utter sh*t. Banging headache, all shakes, and feel nauseas.
