I've been told I should be drinking 2 litres of water a day. I assumed this included all liquids, which would be fine, as I drink gallons of green tea, lots of soup etc, in addition to a reasonable amount of plain water. My only real vice is Diet Coke, which I don't buy for the house but do drink if we go out.
DH reckons I shouldn't be counting anything except plain water when I add up my intake. Surely this is wrong?
