My grandfather was a drunk, but a weird one at that. He used to drink a couple of times a year, for two weeks at a time. He used to get hammered and stayed drunk for two or three weeks, abusing (although not physically) everyone around him. Since me and my parents don't live with grandparents it didn't affect ME that much. But my brother, who is closer to them had to take **** a lot of the times. Moving on, I am in a period of my life where I drink a lot. There is some unhappiness in my life (the reasons for which I will not discuss here) and I found that the alcohol and cigarettes keep it away. I know, I know, but that's what is what makes me feel better these days. My question is, are genetics involved in the process of becoming an alcoholic?
