The drug companies want people to take prednisone for adrenal exaustion because it causes pretty much every disease so they will have a lifetime patient. When I and many other people stopped taking antidepressants , we felt much worse ,but this did not mean that we needed the drug or that it was improving our emotional state. The fact that people (including myself) feel much worse when they stop taking prednisone means that the drug is causing , not curing, their health problems.
A woman I know told me she had back pain from a car accident that would not go away until recently when she had a steroid shot. Steroids damage joints rather than healing them and just because she feels better for now does not mean she wont be harmed in the long run.I think most illnesses are caused by medicine.
