I play a Dryad, not a Stone Elf, so the character reactions are a bit different ~.^ If Amory drinks alcohol or an intoxicate she tends to get more giggly, blunt, and slurs her speech. But a lot of it depends on -why- she's drinking. Her reactions differ based on the reason, the atmosphere, and the group.
If the drinking is heavy, I also like to rp a hangover the next morning.
