sounds like die-off to me, I too get aches and a feeling of flue plus worsening of brain-fog. You have to make sure you are moving your bowels regularly, and drinking lots of water to flush out toxins. If you can eat a more moderate and simple diet. I'm no expert as I'm still sick after years of trying to get better, but slowley I progress. I think with parasites we are all different and what suits one person is different for another. Good quality vitamin c powder has always helped my die-off symptoms.
