re: What’s your go-to remedy for diarrhea?

When I was in middle school and probably 9th grade I had IBS that would always hit when I got anxious about being in a situation where having to take a poop would be embarrassing, pretty much every morning before school and bus trips to games in every sport I played. During the time when girls become of the utmost importance the worst thing in the world is raising your hand in class, asking to go to the bathroom, then coming back outside of the time frame of a piss. My Dr gave me a pill that was taken sublingual and it put my stomach to sleep, no idea what it was called but it was a miracle.
