I had a similar experience. I think it released loads of mercury which was previously held hidden in the body. After lots of searching I'm also focussed on nutrition. Dr Morse (has lots of Youtube videos) seems to offer the highest truth in terms of nutrition. The important thing, for metals, and anything really, is to make sure the kidneys and lymph system are working properly, and many people's aren't. If kidneys are not working optimally, then any metals you detox, or any toxins for that matter will be shifted around the body and not be able to be filtered and removed from the body. Dr Morse recommends fruit and herbs.
