For a few years now my ability to tolerate red wine has decreased. I don't mean hangover, I mean immediately feeling ill after drinking a small glass (or often a few sips). Tonight I had one very small glass and I felt odd and then was sick immediately. It isn't alcohol in general as I often have one or two gin and tonics with no effects.
Weirdly, occasionally I manage to find a wine that doesn't have this effect. Anyone else developed an intolerance like this?
