Hi @loveofdogs and welcome @donnam7900,
I have the same problem with coffee. Good for you for making the necessary changes to help you feel better.
Donna, You'll see I moved your post to this discussion: IBS—Change from -D to -C: https://connect.mayoclinic.org/discussion/ibs-change-from-d-to-c/
so I could introduce you to members like @loveofdogs, @linn1, @jackiem95, and @thull who have all dealt with their IBS issues and may have some suggestions for you!
Here are also two other conversations you might be interested to read, as well.

Have you modified any of your eating habits or any other aspects of your lifestyle to help with the diarrhea?
