Yes, drink one glass of water every waking hour consciously before getting into a long term health program. This would mean that you will have 14 to 16 glasses of water every day. In the beginning, it will be uncomfortable with frequent visits to the restroom. But soon, your body will get used to the increased hydration.
You will see increased energy and lightness even within a week. Keep going on with it and share your experience after doing this consistently for a month.
