Bex, I used the Andy Cutler protocol, on ALA only. It worked well, and I intend to continue using it when time is right. I found that 20 mg per dose is the maximum I could tolerate. I always get a bit better after each major salivation event, but my adrenals get a bit screwed, so I don't want to add up on that load with chelation, since it occurs so frequently. I only get worried when I don't salivate, because then I know my body isn't doing anything useful, even though I'm still not well. It's a kind of a relief for me that the salivation always returns.
