I’m scared of the day I get my first hangover

ok I’m 19 get fully blackout drunk regularly. no food no water the day I drink 5-7 shots vodka (if I remember correctly and I probably don’t) sleep at 2-3 am. Yes I’m fully aware bad habits but

Then I wake up at 7 am (usually I sleep till noon) go to the gym, organize, get more studying in. NOT HUNGOVER

I’ve been doing this for a few years

once tho I did throw up for an hour in the morning ( was it a hangover idk) but afterwards I just got up went to the gym etc

I’m scared IM TERRIFIED of the day I wake up inevitably hungover. I love drinking I’m not ready to stop
