I'm really sorry it's not working out frown.

What are you on? (ALA and DMSA together? Or one of them?). What dosage and what timing?

Some people have to take a smaller dose and take it even more often to control side effects. Some may simply react badly to one or both chelators regardless of what dose/timing they use.

It is also important to support your body during chelation with appropriate supplements and diet.

It may well be the DMSA itself. Oral DMPS maybe a better and more tolerable option. But I'd still be interested in the dosage you're on and the timing.
