Hey, so i am having my first milkshake with double water. How much is 20oz cos i think i have having maybe .65 of a litre(only know litres!!)..... and all i can say is yuk!!! Its made my fav choc milkshake taste like muddy water!! Is that roughly how much water you have been having? Does it get better? I actually enjoy having my choc millkshakes, but i am struggling trying to get this watery one down! Oh well, it will be worth it in the end
