Ah ha found it: (In relation to comment in my previous post - Nights like this.)

'All patients receiving chronic glucocorticoid replacement therapy should be instructed that they are “dependent” on taking glucocorticoids as prescribed, and that failure to take or absorb the medication will lead to adrenal crisis and possibly death.'

Great news. So when I am caught listening to my neighbour around 12 in the afternoon, do I suddenly rush off to take my pill in case I go into adrenal crisis??

To be honest that does sound a bit dramatic; I know I don't feel quite right if I don't take my pills on time but I don't think the reaction would be so severe so quickly - I know because I have forgotten to take it until a couple of hours late on occasion!
