According to the Bang! New Moon Card "New Identity":

At the beginning of their turn, each player looks at the character he is using to keep track of his life points. He may switch to the new identity for the rest of the game, starting with 2 life points.

Does this mean that if you switch to the new identity, you start off with 2 health and that is the maximum for that identity? Or can you use beer/whiskey/etc. to increase your new identity's health up to the maximum on the character card?
