“I found the cubes very strong and sweet. I ended up using a half cube or even a third. I checked the sweetener and it is Sorbitol on all the flavours I was sent as taster pack. Sorbitol has known health problems and an unpleasant taste for some people, so it’s not something I would choose. The website says you also use Stevia or even no sweetener at all. I couldn’t find any flavors that didn’t use Sorbitol.
Looks like Vidrate may be more suitable for me, which is a shame as I like the handiness of Waterdrop.”
