Neurons

A new study says that a glass of wine changes the proteins "expressed" in the neurons and forms a craving for another glass.  But if you don't have a second glass for about an hour, the cravings go away.  I don't know any drunks who wait an hour after they begin the first drink.  But for normal people this info can remind you to pace yourself.  After a couple of drinks too quickly, the memory is affected.  For an alcoholic it means that they forget the horror of their last debacle.  This would also explain why people forget who they are.  Consider the drunk who gets irate that their self-importance is being ignored, and says, "Do you know who I am!"
