Are you serious? First of all, the reason the drink becomes more potent is because the SUGAR is FERMENTING which means the sugar from the juice is turing into alcohol, which will leave little to no sugar left in the drink in the first place. And secondley, even if there was a sugar alcohol mix how would that make you throw up? Have you ever heard of twisted tea? or perhaps rum and coke? or make even redbull and vodka? Have you ever thought about what one of the main ingredients in these drinks are? SUGAR you stupid fucking barbie.
