So, my experience... I was on a diet that used meal replacement goods, all of which had sucralose, xyletol or other sugar alcohol. I had horrible results with my pouch, and my GI forced an abrupt cut-off of ALL sugar alcohols. I can only use aspertame per Dr's orders. Be careful because sugar alcohols are present in A LOT of foods. Even Monk Fruit sweetener and Stevia sweeteners are often combined with a sugar alcohol (i.e. Xylitol, anything ending with "ol"). Just my 2 cents worth.
