Has anyone tried zsweet? www.zsweet.com They say it's an all natural, zero calorie sweetener without an aftertaste. It's made from erythritol which is a sugar alcohol. They say it doesn't have any digestive side effects, like other sugar alcohols.

I've had yogurt sweetened with erythritol (stoneyfield farm light) and it did seem to taste ok, but I only had one.

zsweet and ztrim? what is it about 'z's that's so appealing to the dieting community?
