How can I prevent hangover blackout?

OK so basically I’m a uni student and in my first year ,everytime I drunk no matter how much I would remember everything from that night the next day . ( I don’t actually know what I used to do different ? Maybe I used to eat more before drinking?) Anyways come second year and everytime I’ve gotten drunk I’ve completely forgotten my entire night’s. I’m tired of forgetting everything and also having to have people take care of me as I’m drunk and not even remembering. The thing is I barely eat on the days I drink (cuz i cant afford alot of alcohol and wanna get drunk faster)so obviously I’m gonna change that and try to eat more (maybe 2 hours before drinking to prevent throwing up?) . I read that I should drink more water as I drink (I always drink alot of water right before drinking but I normally don’t drink any water while drinking) anyways is there anything else I can do ? Cuz I want to be drunk for fun but not to the point that I’m becoming a danger to myself and others.
