Yes, to much water in chinese medicine is not recommended.
I drink 10-11 glasses a day.
Balance every way is the key. Candida have nothing to do with high blood sugar, its all about Calcium/Magnesium/Potassium/Sodium/Copper/Zinc balance , but its not all. Even if we have balance , too much vit C can cause low Copper, high copper can cause low vit B6 so low stomach acid will arrive ....
