After I spent many dozens of hours reading various viewpoints I settled on Cutler's protocol. It seemed to be the most conservative and safe method I could find. It also seemed that few people reported nasty long term sfx and many were reporting long term gains.
I've been in the chelation groups for two years now. Some of the saddest stories I've heard have been from those who actually had a rather serious mercury problem and used cilantro. It seems that it actually contains a mercury chelator and it may be able to move mercury across the blood brain barrier--in *both* directions.
