>I have no real way of knowing. Dave's writing does smell a good bit like a snake oil salesman's, however. It's a little too good to be true in every last detail.
It just occurred to me that you might have been referring to Dave the trucker, not the author of the kidney cure pages. I'm not good at recalling names, and that's who I was thinking you were talking about. Anyway, the pages from the kidney cure person are what bother me, not Dave the trucker. I've never read anything written by Dave. Dave gives no impression whatsoever of anything other than someone who wants to talk about his weight loss and improved health.
