I don't know personally, but I have heard good things from friends about the Kinoki (sp?) pads that are sold at Walgreens and similar places. From what I understand you tape a pad (similar to a 4x4 gauze drsg.) to the soles of your feet when you go to bed. Overnight the pad "draws out" toxins and you can see it on the pad in the morning. A few of my friends have tried it and said it worked well. One said you have to do it a few nights in a row to see a big result, then once you wake up with a clean pad you can stop and do it once or twice a month. Like I said, I haven't used it myself, but maybe it's worth trying.
