Dudley, I respect sosick's right to take the DMSA however she wants, but to advise you to do the same is not responsible...with all due respect SoSick. The point of Andy Cutler's protocol is to keep the mercury moving out. Not easy on you to do his round the clock chelating, but it IS safer because it keeps it moving and going out. There is some redistribution with stopping the chelating that way at the end of the cycles, but if you take it randomly or nightly it is possible to do much more damage that way. Andy's method are very well researched and I'm sure there is an explantion why she gets temporary results with feeling better. Longterm it is not as safe, though. Mercury chelation is not something to take lightly. Its one of the most if not THE most poisonous metals on earth.
