> If the DMSA continues to do nothing should I up the dose again?

Impossible, it is doing something. You might eat some cilantro when you take the DMSA though to give it a kick (or use the ALA), don't overdo the cilantro and oy veh, you are taking a lot of DMSA already. Too much chelation can overload your kidneys so do not overdo it.

I would add some fiber to your diet to make sure you don't get constipated from the ALA. You'll smell the metal when you flush the throne and you'll know for sure something is happening.

eat well drink lots of fresh filtered water.
