Beer certainly exacerbated my symptoms. Alcohol has become a much-less-often thing for me (mostly because you can't really have 'a quick pint'). I've benefitted most mentally here though, I think? You don't realise how often you have that post drinking booze-blues (even in the most minor way) until you don't have it very often.

Coincidentally, cleaner alcohol (vodka) seems to minimise the mental and physical hangovers far more than drinking beer.

I pretty much don't. Although I like to taste a glass of different types of beer when I go to a new region (here in Europe). I have noticed that it does trigger the IBS symptoms roughly 40% of the time. Thanks for the comment. I think I'll give up on the tasting because like the parent mentioned IBS is miserable.
