As per your vast clinical experience & knowledge, which SSRI is most suitable & effective at treating both IBS-C and Social Anxiety Disorder? Have both diseases since childhood. Tried Prozac & Seroxat as prescribed by Doctor. Prozac 20mg didn't work for Social Anxiety, Seroxat 20mg worsened the IBS-C and it work very good for Social Anxiety. Didn't tried any other. So I was wondering which SSRI or any other drug would be effective for both IBS-C & Social Anxiety?
