Potentially this is a problem. Alcohol is absorbed into the body at a slow rate and if you pour more down your throat than the body can disperse you end up drunk.
From what you describe the body is not successfully coping with the dispersal of the alcohol and that indicates a liver issue. See your GP immediately.
This is why it is better to enjoy a sensible drink, couple of pints over an hour than a session. The body needs to deal with the intruder, but of course you will not get pi$$ed. Is that so bad?
