You'd likely have supraventricular tachycardia with palpitaions, break out into a sweat, get nauseated, throw up and tbe made to clean up the mess. After you recover from being dizzy you'd probably get a headache and feel awfull for the rest of the day. Better to just order the latte with an extra shot of espresso. ...Read more
