I know what u mean about water I used to filter mine because there is so many nasties In it. Where I am now I can't filter it because its so bad so I buy bottled spring water but I don't have to drink it so cold because it tastes nice anyway. Very cold and very hot can be shocking for our internal system apparently healthiest way to consume is similar to our body temp. I still think one coffee a day is too much but u know what's best for u!
