These could be "liver" symptoms rather than "candida toxins" symptoms. When you start killing candida in good amounts, your liver is necessarily overworking due to increased candida toxins.
Taking milk thistle alone is not enough to take care of your liver. I suggest coffee enemas, liver flushes, lemon juice and beet juice, even though quite sugary the benefits outweight the Sugar issue. Also, be sure to have at least 2 good bowel movements per day, and consider also taking activated charcoal.
