I have regular bouts of what I assume to be heartburn: discomfort behind the lower half of my sternum.
It only really bothers me with liquids, even a large batch of almond milk smoothie, that I made the other day. Wine gives me a certain amount of discomfort, but beer really gives me trouble. After two or three pints I get quite intense pain, and a need to vomit. It feels like my whole system has backed up, and that my intestine's won't let the contents of my stomach through. If I am able to vomit, it tends to be clear liquid with no food in it.
It occurs to me that drinking beer involves greater volume, so may put a strain on things, though it also occurs to me that beer contains yeast, especially unpasteurised cask ale.
A possible lack of stomach acid has also occurred to me: recently I had an extremely proteinous meal of eggs and salmon, and I still hadn't digested it six hours later.
Any clues as to why drinks should disagree with me like this, and not food?
