Welcome @tkhardy01, I moved your post to this existing discussion:
- What was your experience with duloxetine (US Brand Name; Cymbalta)?: https://connect.mayoclinic.org/discussion/duloxetine-us-brand-name-cymbalta/

I did this so you can read previous helpful posts and easilyconnect with other members like @d13 @regalrottweilers @ess77 @naturegirl5 @johnbluffside @duckee @maggie1960 @pattykakes @luv2hike who have experience with Cymbalta. Some have experienced similar side effects as you describe "diarrhea, feel funny feeling, confusion, nausea and very jittery."

Have you talked to your doctor or pharmacist about the side effects? How are you feeling today?
