No hangover after binge

So I work a job that once a week I have 4 days off in a row. With that being said as a 23yr male who enjoys alcohol I have around 8 beers 3 of the 4 days I’m off. I have it figured out to where I drink the first night and I’m hungover the next day (headaches mostly) until I start drinking again around 5pm, the next two days that I drink I don’t get hangovers. I’m just wondering if anyone else experiences this?
