I don't think it's an either/or decision. Depression and meds are much more complicated than we often hear them made out to be? Throw in other illnesses (your MS) and lifestyle problems and who knows what "exactly" might be causing/contributing to one's depression and how to fix it?

I always try other means to solve my problems before I go the doctor route, especially the meds route. I think my body is much smarter than all the doctors there are and that we (humans) haven't learned enough yet to understand all we need to know to really understand how healing works.
