If anyone drinks too much they change and do or say stupid things it's just the way alcohol affects the brain. Being an alcoholic is not so much about your behaviour once drunk. For me it's whether I have a choice after a certain point whether to take another drink which I don't. It's also to do with a mental obsession I have my mind will always take me back tote first drink no matter how painful the previous consequences have been.
Only you know if your alcoholic, try stopping for 1 year if your alcoholic you would find this extremely hard.
