"Can you or somebody explain the kidney thing? Is that why I've been so immobile/tired? Thanks again."
As much as i love Vidda, i respectfully disagree with her on this :).
Actually most experts advise drinking only to thirst Catch22, which is exactly what you are doing and too much water (water beyond thirst) would force your kidneys to work harder than necessary, detracting energy from the cleansing and healing of your body.
