Everytime I talk to someone about this lately, it seems they've gone and done a bunch of research online about it. I figured I could save people some time and attach some links for their reading enjoyment.. ha ha!
http://www.pkdiet.com/ this is of course my favorite site, as it has so much detail into what is good/bad for my kidneys/liver now, recipes, etc.
http://kidney.niddk.nih.gov/kudiseases/pubs/polycystic/ great info
