Memory loss after 2 beers already

Hello there! I’m male, 23 Quick and easy description, I start not remembering parts of my night (conversations especially, also if smth specific happened) quite fast. I’m not a lightweight, but I started noticing that after 2 beers already, my memory starts losing/not acquiring things that happened throughout the night. This wasn’t the case earlier in my life, I was wondering if anyone could know a possible reason? Eating too little beforehand? I know memory loss is connected to consuming alcohol but I know no one as affected as me, some of my friends can get black out drunk and remember EVERYTHING. Thanks you guys already!
