Mighty,
if your body was totally free of toxemia, then all of the bodily energies would be focused on healing and healing alone.
It does take some energy to detox and the more toxic anyone is, the more energy is taken away from the healing process.
Your tongue is clearing and becoming pink again.....a good sign that toxemia is far far less: the cleaning of the tongue usually begins at the edges and works its way into the centre as in my own case.
Just make absolutely sure that you drink water only according to thirst: excessive water-consumption leads to the flushing of electrolytes from the body, as while eating.
Keep a note of any changes in symptoms (if you have any) and let us know asap.
