Amm... "get horny drugged high up" for what? And why it's easier if you can just attack a little one without resistance and take more profit per sec and just sleep again inside Elise house? It literally can be done all in his home especially when you have a pitchfork at the beginning.
you get free fish for doing it this way and you can do it as any persona not just normal and nympho and since fishkind only go for vag in prostitution you will find that it is fairly easy to just repeat and when you finally are full and ready to leave the map you will be able to cook up the fish before you go and also be able to immediately beeline to elise since it will be daytime
