My GP put me on a quick reduction of dosage. However, within a week or two, my own ability to make cortisone was reduced, so I did not have this as extra. I started to have my symptoms back but my GP was adamant that, because I had said I was so much better, she could not imagine that the dosage was not sufficient. So beware. You might feel wonderful for a couple of weeks, but when your cortisol is not being produced, you might need a higher dosage.
