Hi Joanne. You seem to be a bit ahead of me with treatment so as time goes by may be able to give me some advice? I also work in a managerial position in retail; nightfill manager, which is 8+ hours of constant physical work, lots of heavy lifting and the stress of managing staff. Don't know if I will be able to' or want to, return to my previous position. But don't know what else I would do. I am 50. I don't like the constant tiredness of night work but do like the absence of customers, as we're shut. I will be interested in what you do. Sue.
