I Get Sick And Have Diarrhea Every Morning. I Had

I get sick and have diarrhea every morning. I had this back in June of last year. My gastro did colonoscopy, endoscopy, pancreas testing, stool testing... CT scan. Had me try anti nausea meds, budesonide, dicyclomine.... To no avail. It stopped in August. It started two weeks ago again. I continue to lose weight, eat but mostly bland and have little appetite. What could be wrong? I take klonopin, synthroid and Zoloft. Zoloft was discontinued, in case that was causing. It wasn't. YYYY@YYYY
