The reason why you should take it easy is that your body has started killing the parasites, candida etc. that has accumulated in your body. That's why you feel like crap.This will take a long time, there is no easy way out. The mercury leaking out from the fillings makes some of us sitting ducks for the parasites and candida, the body allows to them to multiply and dominate in our bodies, making us sick. The more you take out fillings, the better your body will be at dealing with these parasites, and the more crap you will feel from the die-offs. The last filling removed is sometimes the one that really makes your body going into a killing frenzy. That's why it is better to retard your body by keeping some fillings in, while letting it detox and kill off those parasites in a more slow manner. Then when you take out your last fillings, there is less work to be done, and it might just be a bit more managable.
