So last night i drank alchohol for like the first time,,,,?

I drank like most of the g Smirnoff bottle. && then a some Bud Ice. I DIDNT GET BUZZED. At all. I like downed the whole bottle and i din't get buzzed. I had some bread before i drank cause i figured i might not hold it down but i did. And i don't see the problem. How much do you have to chug before you get tipsyyyy?
