I don’t get hungover

Not sure why, but I don’t get a hangover. Never have. If I have too much I just wake up and puke and I’m fine. If I drink high sugar drinks, I will get a headache only, but that’s even if I have sugar without alcohol. Saturday I got hammered. Started at about 11am on Miller lights (6-7cans) and switched over to Biccardi and diet pineapple juice (was the house drink at the bday party I was at) at 2pm until 11pm. Went to bet at 12am and woke up at 8am feeling like I’d been drinking water all day. It takes a lot for me to get hammered and my friends usually can’t tell. They could tell Saturday. Is there something I can take so that I don’t want to keep drinking once I get started since I’m never worried about being hungover?
