@misscallie: I'm not sure about DMPS since I haven't used it. The Cutler Protocol uses DMSA which should be taken every 4 hours, including at night. I know there is at least one person on this list who is using frequent dose DMPS. I believe it's Sadpanda, but I could be misremembering (my memory is much better now than it was when I started chelating, but far from photographic). They could give you better advice than I could on this subject.
@Oak775: As you like. I would just like to say that my main regret from all of this is that I spent too much time on trying to find a candida-only cure before tackling the heavy metal problem. Actually, my biggest regret is that I should have told my dentist not to put that silver poison in my teeth in the first place.
