I have gradually increased to 8-10 L daily ... I posted something in my log on why I feel this works for me & my situation ... and I don't feel like looking for it.
Sure can deplete sodium ( & other harmful issues) , but not for me, my blood levels and the 'works' are tested monthly so I am luckily able to track certain things to make sue I am not doing more harm than good ... again I am NOT average by no means.. Yup my doctors just love me
