Water is needed to wash out toxins. If your body is not excreting them, you can drink all the water you can and it does not help. Can you explain why you say about fatty acid related to the skin and tongue. Please explain this.
I feel you have a liver problem. Flushes will help but if it is not working right as mine is lemon water for the rest of one's life is the only way to get it working right. I wish you had someone close by that could test you as I do.
