Alcohol intolerance ???

Im wondering if any one else has had any similar experiences with drinking or know people who do??

im south-east asian but wouldn’t say i usually get the “asian flush”, however last night after drinking two doubles of peach flavoured vodka and mixer i noticed my face went super hot and i had red patches all over my body, as well as my heart beating faster. these are symptoms for an alcohol intolerance but what i find strange is i would say i drink quite frequently and the last time i had a reaction like this (and the first time) was about 8 months ago when i had peach schnappes and my body reacted a certain way. im completely fine with other peach flavourings things and peaches themselves. does anyone else have a certain intolerance to a specific by product?? anyway i kept drinking (other alcohol) that night and it went quite quickly…. but these are not the only exclusive times i’ve had peachy-alcohol before so i really don’t understand !
