Sugar Free York Peppermint Patties have sugar alcohol(s) in them (my husband gets them sometimes). The only thing worse than a gall bladder attack, for me, is a dose of sugar alcohols. I definitely get the loud rumblings and fluttering in my guts. I mean, my husband can clearly hear my guts making noise. And it feels like I have a dozen small birds flying around loose in my intestinal tract. The D is normal (no bile), but it usually stinks to the high heavens. The definitely cause gas in people because I can tell when my husband's had some of his candies; he gets terribly stinky gas and a lot of it! When my mother first discovered the sugar-free chocolate, she had a number of Easter eggs (even gave the dog a couple). Then she went to church. Boy, that was the longest hour she'd ever had to endure! She said she had such terrible gas cramps but didn't dare let it out in church because they were so terribly stinky. The dog got thrown out of the house that day too because she was so stinky too.
I know you said that you've been okay taking sugar alcohols before, but I actually built up something like an allergy to them. First I could eat a serving of sugar-free wafers, then I could have only a piece or two of candy without suffering diarrhea, and then I had a lot of D after eating a creamsicle with about 2 grams of sugar alcohol in it, but the last time I accidently had some--1 gram in two pieces of gum--I was in the bed for two days with horrible pain, diarrhea, and the above-mentioned rumblings and flutterings. In fact, it took me a couple of months to fully recover after that last bout because I kept having a lot of pain and diarrhea every day, even though the rumblings and diarrhea stopped. I finally got straightened back out with calcium and upping my usual Welchol dose. I now tell people that I'm allergic to it, because an honest-to-God allergic reaction can't be worse than the reaction that I have. I'd hate to think what 1 gram would do to me now; everytime I have eaten sugar alcohols, it took less and less of them to get a reaction out of me, and the reaction grew more and more severe.
If I were you, I'd put them on my list of forever-banned substances. I even tell my doctors and pharmacy that I'm allergic to them so that they don't prescribe me any in any medicines (some chewables are starting to have it in them--Digestive Advantage is one of them).
