If I drink too much, I become aggressive and mean. It's like a switch goes off in my head and I turn into a monster. I have fought family, friends, and complete strangers while drunk and it's all completely instigated by me. Ten minutes after I go into these rages I am wondering why i got angry in the first place.
Everyone's brains are different and alcohol affects that part of the brain that regulates your emotions. I am just one of those people that doesn't respond to excessive alcohol with pleasantness.
