The feelings of helplessness is the mercury. When I have mercury redistribution that is the FIRST symptom I get! That is why you need to get the last of the amalgams out and then begin detoxing Andy Cutler style. If you don't trust your dentist, then go to another one. Taking supplements infrequently or whenever you feel like it will make you worse. You have to be a machine and take the supplements and chelators on time.

It is more dangerous keeping the amalgams in your mouth, then trying out the frequent dose DMSA. Every day you keep the amalgams in your mouth you are being further poisoned. You have to get through this hurdle, so you can get better for the future.

You should not be chelating with the amalgams in your mouth. If you are trying to chelate with amalgams in, that is probably your problem right now. I'd start on the most basic supplements (if you can) so that your body is ready to detox. I have a feeling that you feel so sick from the supplements because you either 1) have a candida/yeast problem 2) you are hyper sensitive person that is "allergic" to everything.

If it isn't from yeast, then I'd take only 1 supplement for a week. Then if you feel okay, add another for a full week. Do this until you are taking all the necessary supplements. This will also allow you to see which supplements are causing problems.

Other than that you have to be mentally prepared to detox. It won't be easy. But you can take it as slow as YOU want.
