I've used erythritol (on its own or combined with stevia) for nearly 9 years now and have never had any issues with it. I originally wanted a sweetener for some of my low carb baking, but now also use it in my coffee & cocoa, when cooking certain things - mainly sourer fruit e.g. rhubarb, gooseberries, cranberries, and also with some fresh fruit, with cocoa and yoghurt or cream for a sweet, and generally if anything else needs a bit of sweetness added.
It is slightly less sweet than sugar which I find OK, and although it's high in carbs as
@HSSS said it's not actually digested.
The standard granulated form is available in tubs (Natvia) from some supermarkets, e.g. Tesco who often have it on offer, or Ocado. It's also available from Amazon in various other forms too: powdered/icing sugar, erythritol gold (demerara type), or combined with Stevia for a bit more sweetness. Try Sukrin or our UK NKD Living brands for these options.
And finally I had a very few, very mild false hypos early on after diagnosis and weirdly, my body very definitely knew the difference between sugar

which it wanted, and erythritol

which was of absolutely no interest whatsoever.


I had to resort to scrounging around in my husband's sugary stuff to satisfy that craving.
