You obviously don't drink enough. The idea is to drink so much you blackout and pass out.
True I have never really drank and blacked out, maybe once or twice. I did successfully stay drunk earlier this year for 14 days straight all day with no hangover, it was a great time. My body gets really good at drinking when I drink regularly. The older I get the less hangovers I get as well. Normally I only drink 1-2 a week and 1 of those is usually just a beer or two.
