Sounds like it's doing you good in one way, increasing glutathione, and aiding detox and healing, but also mobilising the metals and making you feel a little odd/spacey. The risk is moving mercury around too much and increasing the risk of more going into the brain, which mercury can do because it can cross the blood brain barrier pretty easily.

You have to decide whether you want to keep taking this stuff, if the good outweighs the bad etc. Some people do indeed do well on sulfur and andy admits this. But many can get very sick from it because of the mobilisation of metals....

If you're doing ok, then your body is obviously responding well, then should be fine to continue. Just be wary of certain side effects if they happen though. Mercury is an awful metal.
