Liquor Beer Sicker

Beer before liquor never been sicker? Is this true?
A friend of mine drank a lot of beer last night and then ended with lots of liquor. He was puking for about two hours after that. Is that old saying true? If you’re going to drink liquor, should you do so before drinking beer? Is this a myth?
yeah, its a myth, its the alcoholic content that matters, the one and only reason he was puking was because he got totally smashed
Beer before liquor and you’ll never be sicker
