Dear Jo,
I don't know if I would use the expression 'low moods.'
My adrenal gland seems to stop working.
When I am on 4 days of dex at 20mg a day, then it takes me a full for days to get over it. Then I have another four days of the same, after a four day break. After the second time, I am worse, and there's a day when I can't walk and require a wheelchair. By the way, I am normally fit and can walk a mile without any trouble. The second time each cycle takes me five days to get over. The transformation is very sudden. I go from barely being able to walk to the bathroom to being able to walk again.
