<s>[INST] why do i get heart palpitations after i drink any amounts of alcohol? i used to drink 6 cans in a night and be fine the next day but recently, after a particularly bad hangover, no matter the amount consumed i wake up at night sweating with a very fast heart beat [/INST] Hi.This may not be related to the alcohol, but for now your should abstain from any alcohol.You need to see a doctor for an exam, EKG, echocardiogram to check out what's going on here </s>
