I bought the liqueur but how do I use it?You can buy Viel of temperance and/or premium schnapps, both get her 50% and over 60% drunk.
Also raise her mouth level, cause she wont drink with it too low when the patrons ask her to have a drink.
Temperance will lower all your stats, schnapps does not. So try to get drunk with high stats so there is more action at the start.
Also, how do I progress with private meetings? I stopped at the first one!
