Serious question: Are you Asian? If so, you might be experiencing the so-called Asian Flush (
https://en.wikipedia.org/wiki/Alcohol_flush_reaction). My SIL is Chinese and cannot tolerate wine because of this.
Personally, I can handle white wine without any problems but red wine gives me migraines. I suspect it's got something to do with the sulfates but I don't know. Even the smell of it bothers me.
