I also have some IBS attacks and can't figure out why. Sometimes certain foods or snacks bother me and sometimes not at all. Metamucil always made me very gassy and bloated but the Acacia is not at all. Also once in a while I eat a granola bar but I think there are whole oats and maybe nuts in there that can be a trigger? Not sure on that one.
And if you would just stop holding your mouth the wrong way you would be fine! ha ha
