There’s a type of sweetener used in candy that does this. I know it’s sold on amazon. Because the reviews are hilarious. Might wanna try diarrhea candy in google... also might wanna private search that, come to think of it

Edit: found it, and the reviews do not disappoint!

You might want to try amazon. Here's a link:

Truly an excellent example of modern rhetoric and prose. The writers of tomorrow aren't training in colleges and writing schools- no, they're busy writing Amazon reviews about sugar free gummy bears.
