If ya hate plain water why dont you do what a few of us on here have done..contact your local CD rep and get some water flavouring from them..my rep was totally fine with it and i know starlight does the same.
Too much plain water is so hard to stomache ...I've now got berry and a sunshine orange one to choose from..both yummy and at 7 quid a pop not too expensive as the tub lasts for ages xx
