To answer both questions, it really depends how drunk you are. To the extreme of black out, what is the experience like? You wake up somewhere hungover or still a bit drunk not knowing how you got there and not able to remember anything past a certain moment. How much control did you have? Not much. In that state any flying by emotion or idea can really take charge regardless of how bad it is. Most don’t remember doing or saying any of the things they did or said.
