One key thing is to drink plenty of fluids so that the ureters, and eventually the urethra, can fill frequently to their maximum diameter which is, hopefully, bigger than the stone, and allows the stone to float down the pipe.

Unfortunately, that means lots of bumping and scraping while floating, which is kinda like riding down the river in my boat.

The fact that Brewer is feeling the stone move is a good sign so far. And he's not the first or last person to self medicate with beer.
