Believe it or not I started having this reaction last year anytime I drink ANY alcoholic beverage whether beer or liquors.... and NO not from drinking ALOT!!! LOL. I actually drink only occaisionally & not much even then! Mentioned it to the Dr on my yearly & was told it is fairly common - that some people flush with alcohol exposure & that mine was most likely from body chem. change due to my age (40)... DW says it is a good reason NOT to drink - ever!!! But my blood pressure & all of that stuff was perfect. Mine just flushed my face a pretty bright red - but no other symptoms. Since then it happens every time to some degree. Although note that I began taking thyroid med that same year.... Dr says no correlation .... but...
