Wow, I'm mercury toxic too. I've been chelating using the Cutler protocol since Nov, 2011 and just recently added Iodine to assist with the detox.
I suffer from scalp odor and the first few days of iodine, the odor was off the charts. It has calmed down since then. I've had headaches too even though 14 Amalgams were removed in 2004.
Thanks for sharing and confirming my suspicions about mercury intox. I look forward to reading about your experience as well.
