No offense, man, but you sound like a loser to me. You should never be getting black out drunk as an adult. Never. That you even have to ask the question suggests you have a warped view of what drinking is supposed to be like. Your health is most likely sht from all the alcohol you consume too. I am not joking. Alcohol destroys the lining of your GI tract, so if you're drinking regularly, your body cannot absorb nutrients properly. I could go into a long lesson on B-12 deficiency, but instead I'll just say your brain is probably already slightly damaged.
If you're concerned about alcoholism, give it up and see if it's difficult at all to go a week without any booze.
