Yes of course. I keep chelating and it goes away. You are going to notice effects when the stuff is being pulled out of hiding and running in your blood, it's like a fight in there, good nutrients against bad.

I keep supplementing, eating healthy, drinking lots of water.

Yes I take selenium, about 300% daily recommended value, with a day off a couple times per week. The selenium is quite helpful. I mostly chelate hard at bedtime, and eat/supplement during the morning/day. Lots of fruit smoothies with vitamins tossed in.

chlorella too helps me a lot. I use that during the day instead of DMSA.
