"I'm scheduled for 13 rounds of IV Chelation therapy for the Heavy Metals and ofcourse, this is out of pocket, ouch!"
I found a product called Detoxamin which is a suppository form of chelation therapy. It's supposed to work as well as IV chelation but Much cheaper. You might want to look at it. I don't have their website but maybe you could do a search for it. It was highly recommended.
I seem to remember Dr Mercola doing an article about leptin, you might want to search his website: http://www.mercola.com
