Hey, Vanmel! I was wondering how your Oxypowder cleanse was going. Have you gotten anything out that looked like it might be mucoid plaque? I've been taking it for a while too. I was hoping to get some black sludge out, but I didn't. I did however, get some brown sludge out, and the plaque that I passed on P & B was brown too, so maybe that is it.
Anyway, regarding the metallic taste, you might ask Shelley. You know she has an awesome site now, www.askshelley.com. She is full of good info! Good luck!
