Feeling fine so far with no herx. Since zapping my energy levels have exceeded to the heights. I can manage now with 5-6 hours sleep a night and feel great during the day and still not tire. My skins clear and fresh looking, so my next step is pulsing. Apart from taking Colloidal Silver I also take d-calcium elenolate providing oleuropein from olive leaves which could be the reason my no ill effects. Chlorella keep pollutionn with metals, mercury down.
