actually, the whole "cranberry is good for the urinary tract" thing has been debunked, I recently read. it was always anecdotal, but they apparently finally did a controlled study. but it is wet, which is good. hydrate, hydrate, hydrate. I had had a few stones before I moved to the Caribbean in '95. but I really had to change things up, once there. mostly Amstel light. lots of Amstel light!
