Has anyone hear of any fruitless side effects of intake the sugar substitute Xylitol?

I like the flavor and I hear it is automatic. But it seems too upright to be true. There has to be some sort of impossible side effect.Has anyone hear of any fruitless side effects of intake the sugar substitute Xylitol?
If you eat too much it can enjoy a laxative affect., but you have to devour a lot for it to do that. Less surrounded by kids though. Found that out after my 2 year old ate give or take a few 3 handfuls!
terrible gas is the side effect.
any sugar substitutes enjoy harmful effects. they are man made, or the chemical build up is changed by man, so your body cannot digest it. they just come to an end up getting stored in your body, and label you larger. unless you are diabetic you should use natural sugars.
