Thanks to all who have replied to my post and given advice. I will certainly get my next blood test done early in the morning. That's easy for me as I work in gp practice so will ask a colleague to do it before we start at 8.30. The exercise thing is a big one for me. I hate being overweight and want to look better. I also want to feel well and have more energy and less pain. Does anyone know if addison' s is hereditary? I am worried about this.
