Rather than go for more testing for my chronic, daily diarreha, I tried taking anti-anxiety meds. The D stopped in 48 hours. That told me it was anxiety related so I started seeing a psychiatrist, doing yoga and relaxation and taking Effexor XR which is both anti-anxiety and anti-depressant. Even under the biggest stress--like my father being rushed to the hospital day before yesterday with a possible stroke--the D did not come back. So amazing. Take care.
