The alcohol is probably dehydrating you. Dehydration
can cause tachycardia
(rapid heart rate
) which can make your heart feel like it's pounding out of your chest. I would say to drink water whenever you drink alcohol, a 12 ounces of water for every beer you drink. Take it easy and be careful. If this happens every time you drink, I would say that you should just not drink at all. I don't think it's an anxiety
disorder because you haven't really mentioned any other symptoms of anxiety. take care.
