Don't worry too much, many people have redistributed mercury from many different things, we have all made mistakes and it's very easy to do. The brain fog should start to improve later on as things settle more, but if you're concerned, you could start trying the DMSA or DMPS according to how I suggested, which might help with what has occured.

But agian, brain fog can occur even on safe chelation. It's not always the brain that has been affected, the liver can be too and can cause brain symptoms! So sometimes brain symptoms can be caused from the liver area. It's pretty hard to tell what is doing what.
