Excessive drinking can cause problems. Alcohol is decomposed into ethanol in the liver, but the capacity of the liver is limited. Beyond this limit, alcohol will remain in the blood, which will have a negative impact on the central nervous system and muscles. Frankly speaking, if you drink too much, your muscles will break down completely. In fact, people with alcoholism will lose their muscle mass sharply. After hard training, there is no point in exercising if you have a hangover all the time. Therefore, it is ok to drink in moderation within the range that the body can bear.
