I was wondering if it is common to have GI problems with sugar substitutes. I can't eat more than a few bites of anything that advertises as "sugar free". It's not just one artificial sweetener, it's almost all of them. I guess it's just another thing to add to my "can't eat" list; popcorn, nuts, seeds, any fruit or veggie with a peel, dark colored drink, etc. UGH!!
