i think the impact is not for short term but its always in long term, drinking alcohol is not good for our health because soon or later, our health will be drop and if we continue to drinking alcohol too much in a day, then our health will be get sick. drinking alcohol is like consume drugs. we are fine for one or two years, but imagine if we still consume for more than five years or more, then i think we can get a ticket to meet the angel of death.
