curing the drunk

I'm trying to sober up the drunk and have absolutely no clue how to start it.

I'm sure the answer lies in the options page under how to play, but if this one is like the others just click on a sheriff or deputy who will "arrest" the drunk and send them to jail to sober up. I'm sure you will need to employ them after they become a responsible citizen. If not, sorry ! Good luck

You can also have a townsperson escort him to the church once you are able to build one - this option doesn't cost you any money.
