The other weekend I only drank 4-5 pints on a Friday night and still felt fairly hungover the next morning, which I attributed to just getting older. But I told a couple friends about this and they said it's probably because I was drinking draft beer instead of bottles. I had never put any thought into this, but maybe it's true if the lines from the keg are old and dirty or something, who knows.
Can anyone confirm/deny if this is true? I've never really noticed or ran any tests on this theory lol. Although I believe there's a point that once you've drank enough beers, regardless of bottles or draft, you're going to be dead the next morning.
