i would look into quick detoxing tips if i were you, that is definitely cutting it close. to start buy some magnesium citrate soon and drink the whole bottle to flush out your bowels, this works by drawing water from your body to the colon to flush it out, thus dehydrating you. then drink water, eat fatty foods, drink more water, eat more fatty foods, then drink more water. the day before find a spa that offers a full body detox spa treatment. this will dehydrate your body again so you will need to rehydrate afterwards again but don't drink anything beforehand, it is best to dehydrate completely. this might seem dangerous but desperate times call for desperate measures
