// Description:
//    Alcohol effects
//    TODO: Retroactive, weakens every hour...
//
// Variables:
//    @taste    Alcohol taste (0~100) - influences exp up
//    @Alcohol   Alcoholic rating (0~100) - influences Attack Speed Malus, Min. Vit and duration
//    ALC_DELAYTIME For how long you are drunk (the delay) - gettimetick(2)
//    ALC_THRESHOLD How drunk you are (the bonus)
//
//    When drunk, attack speed is lowered but exp gain is increased.
//    Attack Speed Reductor: SC_ATTHASTE_INFINITY (reset upon death), SC_ATTHASTE_POTION2 (not reset upon death)
//    Max HP Reductor: SC_INCMHPRATE
//    EXP Increaser: SC_CASH_PLUSEXP (not reset upon death), SC_OVERLAPEXPUP (reset upon death)
