I’ve had Addison’s since 1979. I am taking hydrocortisone, 10 mg morning, plus 5 at lunch and 5 at supper. I also take fludrocortisone 0.5 mg every other day. This seems to work for me. I have a fairly good energy level for being 76 and used to work 50 hour weeks when I was still working. I only need to see my endochronologist once a year. I definitely need extra cortisone when I am sick. Hope this is helpful.
