Some people may have to take the DMSA more often - every 3 hours if they are fast metabolisers. Some of what you're experiencing may still be redistribution if that is the case. I've heard people getting symptoms on even lower doses than 6 mg believe it or not!

Though it may simply be that you are very toxic and it may take alot of time before you can tolerate rounds easier. If you have to stop when thing get too difficult, then definitely do so. Don't push youself to continue if you can't. I tried that and it just made me feel utterly wretched and wasted.

You seem to be doing what appears to be the right things with supplements and diet, though fruit maybe an issue if you have a bad candida problem. Even gluten free bread can, because anything high in carbohydrate - natural sugars, can potentially feed candida if it's bad enough. Including high carb vegetables likes peas/potatoes/carrots/pumpkin/beans etc.

That will be up to you if you want to try restricting them or knocking them out completely to see if it makes a difference. It does make the diet very restricted though. I used to substitute with almonds/brazil nuts and pumpkin/sunflower seeds and sugar free acidophilus yoghurt.

I can't tell you how many times I had to stop a round short because I just felt too toxic to continue. Don't beat yourself up about that. Things should start to improve as you keep trying. It could be that not only are you very toxic, but yeast is difficult also and flares up worse during chelation, which complicates things even further.

By the way, do you tolerate selenium? That was helpful during my detoxification, but there were times when that alone created alot of interesting symptoms due to mercury - which appeared like detox/redistribution. Probably the better tolerated might be selenomethionine. Usually 100 mcg is about right, though some go up to 200 mcg. It has been recommended in mercury toxic people quite alot and a doctor here, studied in mercury and detox, recommended it to me in the early days and it was powerful stuff. I had to lessen the dose and sometimes miss a day or so, because the detox was very strong. It's not a chelator, but it competes with mercury, as mercury depletes/blocks many of these elements - iodine/selenium/antioxidants, essential fatty acids, minerals etc etc.

Best to take selenium away from vitamin C, as apparently vitamin C can cancel some of its effects. Usually 2 hours or more apart. I would take selenium in the evening and vitamin C earlier throughout the day as I recall.

zinc is another one that you might wish to add to the regime here. Another important element.
