Why is the real reason we need to drink so much water on this diet. Is it becasue of the dehydration factor, or has it been proven that the more you drink the more you shrink? I am finding it quite difficult to down so much water and to be honest it is putting me off this diet (I felt the same way last time too and dreaded starting this diet becasue of it). Weekends are worse as in work someone is always making a coffee which I replace with water so it is slightly easier at work. Has anyone got the REAL reason we have to drink this much - I feel like I am drowning!!
