I've always believed much of Baker Joughin's story. But with few to observe him that either lived or payed attention to one person's actions we have generally just his word. There were other accounts of drinking, Storekeeper Foley had some brandy on him, Jack Thayer talked of a man who downed a bottle of Gordon's Gin and later saw the man on the Carpathia. As you mention, there could be a lot of factors combined with the amount one drinks that may play a role in survival; if anything maybe it calmed those folks down to focus (best they could) on the situation and not get so upset that they made desperate choices. Acting on my own or what others have talked about those times when one drinks a lot; I/they don't always seem to remember the night before as clearly as what took place. But that again is a guess based on experiance, something to think about, but it doesn't change the baker's story officially, just a few things to ponder. If everything occurred the way he described it or even most everything, he is another interesting addition to those who tried to help and against all odds found a place among the living!
