As able mentioned in a seperate post; all anti-oxidants will help relieve you of die-off symptoms, molybdenum is one such anti-oxidant. It should be available at your local vitamin stores. There are other anti-oxidants you can get if it is not available.
Another way to reduce or completely eliminate die-off symptoms is to sweat out the toxins via the bodies largest organ, the skin. You can do this by doing a hot tub, steam room, jacuzzi, sauna, or even hot bath.
Die-off time periods can vary person to person. Mine lasted between 8 and 16 days, and I felt pretty bad the first 1.5 months in general. Afterwards I slowly started to get better. Poor thomas has had die-off for months and a few other forum members have had it for a long long time. The websites timelines are generally unsatisfactory because it takes a long time to recover from a cancerous health problem that has plagued many of us for years.
