I heard a very similar account from a guy across email. He was using NDF and telling people that this stuff was GREAT. He felt he was healing from mercury and all was coming right.

Well, I don't know what happened, but not long after that? He ended up in such a severe state, he was mostly bedridden and so ill, he was desperately trying to get help. He could hardly function.

I don't know what happened to him, I lost touch. But the poor guy was a mess and was very upset about what happened and tried to get help from the guy who made the stuff, but of course, he did not get a response.

I don't know what happened after that.
