It is possible that you have acidity that gets aggravated by alcohol. The treatment of acidity involves taking a proton pump inhibitor such as
omeprazole, lansoprazole or pantoprazole empty stomach in the morning. Along with it you can try over the counter antacids. However I would recommend you see a doctor and take medication under a doctor’s supervision.
Chemicals like adrenaline, alcohol, caffeine, cocaine, amphetamines, and other drugs all cause palpitations.
