a typical heavy drinker
As with a smoker, gambler or any other such person, a heavy drinker starts the drinking as an occasional affair for fun and to keep the company of friends, and gradually becomes a dependent on drinks and eventually becomes a seasoned heavy drinker.
Most heavy drinkers lose their jobs, families, friends and money, and become a social menace, and end up getting into troubles with the law.
Of all the health problems a heavy drinker is susceptible to, cirrhosis of the liver, liver damage, is the most prevalent all over the world.
No heavy drinker ever admits that they are heavy drinkers until it’s too late and once the cat is out of the bag, become more and more adamant and refuse to take the help of the family, friends and doctors.
