You'd be dead after 20 shots of tequila or at least in the hospital for alcohol poisoning.
edit- I just did the math. Based on the average weight of Japanese men and women and saying that it's been 3 hours since their first drink, his BAC would be 0.71% and hers would be 1.0%. At 0.4% BAC is where you are at risk of dying of alcohol poisoning, so both of them are 100% dead without immediate medical treatment.
