A German Method is to dissolve the stones and not flush them, works in 3 days and has been known in the USA since 1960 or earlier.
I have been sending the free boolets out about 20 every 2 days and had to have them printed at a print shop in black and white, i couldn't keep up on my color printer. If you want it sent by e-mail, it may work or may not, just can try it and see.
