Hi Welligton,
You sound like the same type of drunk I am. I've passed out under park benches after getting in fist-fights with friends, started most likely because I was hitting on their girlfriends haha. As my drinking progressed, I went from being a happy, fun drunk to a mean and belligerent one. I knew I had to stop because I am a danger to myself and others when drinking. One sure sign I knew I had a serious problem: being arrested by the same cop on two different occasions a year apart.
