Maybe it was the type of beer. I only had one; it was not a "can't hold my liquor" thing. One beer ≠ me horking in the bushes. I just know it happened, and I don't wish it on anyone.
It could have had nothing to do with the beer at all and was just a coincidence that you were drinking. You could have just caught something that made you throw up and then be fine after.
