I started buying these for my husband as he said he needed to drink more water and flavoured water made him drink more. I don't like the flavoured water in bottles from shops as it is way too sweet for me however when I tried Waterdrop's tablets I was surprised at how nice they are to drink! It is definitely making both of us drink more water and I love that they bring out new flavours. We have found that some flavours are not as strong as others but we have definitely found our favourites! I prefer the flavours like lemon, zesty lime whilst my husband likes the orange and blackcurrant. We both love Pink Lemonade so I hope that is here to stay. The only problem I have is choosing what flavour to have! My mum is going through chemo and I suggested she also try them to help her drink more water and she has also said she is very happy. Also they have really good loyalty points system.
