Are you taking molybdenum amino acid chelate? There’s regular molybdenum and the one able recommends; there’s a big difference between them.
If you experienced more die-off after running out of milk thistle; I would look at this as one of the things that are different. Die-off is caused by the liver being overtaxed and the milk thistle heals/protects the liver. There are more liver supplements you can get that can aid in die-off as well.
You can sweat out the toxins just by doing a bath at home; if you have any friends with jacuzzis or can borrow a pass to a workout facility, you really need it to reduce the die-off. I know 24 hour fitness can give you a free 2-week trial of their facilities and they have jacuzzies, saunas, etc.
