You know in all honestly beer isn't that "unhealthy" when taken in moderation. There have been more recent publications on its benefits, which out weigh the negatives.(again when in moderation) I will indeed like most feel like crap after drinking too much, or not drinking correctly if its over a longer period. (such as trading off for water to stay hydrated) But feeling crappy after just one beer could mean you either have an intolerance to something in it, possibly wheat allergy. (you could try sorghum) Or just a touchy body. In either way hopefully you didn't enjoy the flavor so its not a loss to you.
