I've got his book also and read alot of posts about his protocal.

ATM I've got my own protocal that I've taken from all my research. I may try Cutler's in the future if I dont get the results I'm looking for. Cutler's program seems a bit challenging with the every 3 hours thing.

I personally am not going to take any DMPS or what not; read some posts about some bad reactions etc from them. I rather stick to some natural chelating and some ALA.

Some things that Cutler's program doesnt include is the use of garlic and cilantro or even chlorella. He actually says not to use this and emphisizes this.

I think these things can help you chelate although they are harder to measure in terms of amount you need etc ...
But for me; I rather take natural things (and things that are cheeper then something like injections or anything like that).

Check out the yahoo mercury autism forum also; lots of good posts on parents treating their kids (mostly using the Cutler program).

Just make sure you read as much as you can on the subject; here and curezone.com are some great places and also the yahoo forums.
