ELI5: How do people "blackout" from drinking too many alcoholic beverages but remain conscious with no recollection? 

This happens to me way too often so I might as well understand what is happening.

Your brain has to keep track of a lot of different things at the same time.  Part of the brain deals with this "what's going on right now" information.  It's way too much information to store long term though.  So your brain makes decisions on what gets moved into "I should remember this later" parts of the brain and what just gets thrown away to make room for what's continuing to happen right now.  Alcohol messes with the brains ability to move stuff into longer term memory.  You drink enough of it and it pretty much shuts down the process all together, which means by the time you recover from your drunken stupor, you brain didn't save any of that information.
