Yeh I'm on 2-3 tetras a day and I have 3 litres a day. Didn't realise the extra glass was to be had with it tho. That's where I'm going wrong maybe! I thought maybe I was paying for being impatient while poaching my eggs the other day! Ha!
I have also had this this time around not sure why but better than the other way around which i experienced the last time! Think it's the minerals and vitamins and the sheer amount of water I am drinking!
