Once we have tapered down to 5mg prednisone and below, aren't we at the mercy of our adrenals because they need to start waking up and producing cortisol again? I'm not there yet. I just decreased from 9mg to 8mg this morning. Isn't there a morning cortisol test to verify that our adrenals are back to working, or else how do we know they are? I have a rheumatologist (PMR) appointment in two days and I'll be discussing this among the many questions I have.
