what Alcoholism dose to the body

Alcolism is a growing diseas in America and is a physical diseas which i thought didnt make much sense. The American Health Organisation says it is a diseas that efects the whole Family which againg didnt make sense. But i found out at an Alanon meeting that it infects the Alcholics liver and makes them crave it and that when the Alchoholic is drunk is how it effects the family. An Alchoholics liver is missing parts that it needs and terefore it craves Alcohol.
