I feel that way when I don't get enough sleep. I've never been drunk, mind you, so I wouldn't really know. But I lose my sense of balance, walking into walls, doors (can really bang myself up), dropping things and knocking things over. Cannot really focus on things people are saying, or even hold my own train of thought. Maybe that's because my liver didn't have enough time to do it's thing (during sleep)? I'm bad enough if there is one night of only 6 or 7 hours, if I endure an entire week of short nights I am truly a sick mess, I guess my liver takes its sweet time at night to do its job.
Hmm, GOTTA get serious about liver flushing!
