I have been using pads from http://www.purifyyourbody.com
and I have never slept better or felt better during the day. I don't get the usual middle-of-the-day-rut anymore either. My sister-in-law who uses these religiously even sent some in for testing. She sent in a used pad and a "control" unused pad. The used pad came back with all sorts of toxins and the unused came back clean of toxins. I was sold from that point forward!!
The business owner is really nice and responds to every customer. Any questions you have, she will answer! She ships everything priority next business day for free. I really have enjoyed getting these foot pads, and absolutely love the product and company.
