 * Every variant of alcohol provides a +3 luck bonus that is different for every other variant of alcohol; this means that one can obtain a very high luck bonus by consuming different varieties of alcohol at once.
 * if you pick the rank 2 party boy/girl WHILE you're under the influence of alcohol already, the "stats" menu won't show +2 strength +2 charisma etc. Make sure you pick the perk while you're sober to see the effects.
