Before I ask for advice about how to stop drinking, I'd love to know the proper meaning of  Alcoholism?
Alcoholism is basically drinking that interferes with daily life and results into physical and/or mental health problems. 
Omg, that sounds horrible. Are the illnesses from it terminal?
They can be, excess alcohol drinking can affect the brain, heart, liver, pancreas, and the immune system.
What's are the governments of the world doing to ensure alcohol Companys are not producing harmful drinks
They're not doing too much about binge drinking I believe, they are only warning people about the effects and consiering it a major public health issue.
