I have been drinking Willow Mineral Water for nearly three weeks now, and I have been less itchy so we are fairly hopeful that this can help me. Mum adds the water to my meals so they are like a soup, it is too expensive to use in my normal drinking bowl as I usually tip it over before I have drunk the water. The best buy for Willow Water seems to be Sainsbury’s or Waitrose, where it costs 99p for a 1.5 litre bottle.
