I can't find a reference listing diahrea as side effect of Wellbutrin. You are on a considerable amount of benzodiazapines, xanax and ambien which can cause diahrea. You cannot quit these without tapering them. Xanax 3x per day can be problematic. It works only 3-4 hours and people go from periods of great relief back to high anxiety. A xanax rollercoaster. Wellbutrin is not very good with anxiety disoders anyway, so you likely should try something like Lexapro and get a longer acting drug, such as ativan, to replace xanax. Viibryd is an SSRI antidepressant, which may be the reason for it being used with wellbutrin. Honestly, you are the first person I have seen on it, so I don't know all the details. I am reluctant to have you quit it. I think you really need a Personal Physician, likely Psychiatrist to help straighten this out. Take immodium (Over the conter) to control diahrea.
Have a appointment with psychiatrist next thursday- just tired of all the anxiety-will stay on the viibryd for now and tough it out. The diahrea has been ongoing for 2 weeks now
