anyone use liquid saccharin? is it truly calorie free?

I use it sometimes, but don't really use that much sweetener of any kind. Yes, it is carb free. The reason the powdered sweeteners have carbs is because of the filler they contain. At least that is what I have learned from others here. I do use Sugar Twin powdered sweetener in my cream cheese with some strawberry Kool Aid, and drink Diet Rite which has splenda, and an occasional Crystal lite which has nutra sweet, but just don't use much sweetener otherwise. My daughter uses the liquid saccharin in her tea and likes it okay.

I generally use the liquid Sweet-N-Low in recipes, to replace some of the powdered sweeteners(helps to reduce carbs a bit) since too much of it leaves me with a slightly bitter aftertaste on it's own.
