I only drink the minimum but i do know if you drink between 3-4litres is prob better for u for weight loss, but i just cant drink any more than the minimum.
I do like to have some black coffee though and my water does have to have the CD water flavourings. Thank god for the flavourings as i am not fond of plain water.
How do u guys manage 4litres, i am on the toilet all the time just doing 2 and a half litres??
