How much water should I be drinking?
The best guide is your thirst and frequency of urination. It is good to use the restroom every few hours and for the urine to be light in color. This indicates you are hydrated and drinking enough water. Use coconut water and fresh green juice also to keep you going.
If you become very thirsty but are drinking lots of water you may be over hydrated. Add a pinch of salt to your shakes and lunch, substitute green juice and coconut water for some of the water.
