If your die-off is intolerable, it probably means your liver is overwhelmed. You will hit exactly that groove: not feeling so terrible as to want to lie down in traffic anymore, but maybe wanting to lie down on the couch a lot :p The molybdenum dulls the edge a lot, which is what you want. Just keep in mind that this takes a while.
I also never saw the “stringy” yeast stuff, if that makes you feel any better. I don’t think everyone does.
